For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.

About
You play Ethelyn Dax, Galactic Bounty Hunter extraordinaire. Finally settling in for a long-awaited vacation on the resort world of Ctesiphon, the moment is ruined by the surprise arrival of the Black Death mercenary company.

Taking the capital city and every surrounding resort hostage as part of a payment dispute, the mercenaries expected to meet no physical resistance.
Ethelyn would be perfectly content to simply get her money back and leave the resort to sort things out with the mercenaries themselves, but as it turns out the force is led by a shadow from Ethelyn's own past that she can't simply let get away.

The Black Death mercenaries have brought so many troops, clones, drones, and mechs that they expect absolutely no resistance from the resort patrons. You will prove that complacency unfounded.
Take advantage of the mercenaries' inattention with Ethelyn's trusty Data-Spike, perforate them with the versatile Submachinegun, blast them around corners with the Gyrobuster's homing minirockets, or bring out the Jetgun to cut through heavy armor as if it were mere paper.
Ethelyn is highly nimble and can run circles around most enemies who will have to resort to overwhelming force to try and stop you. The game features seven mainline levels built in a non-linear layout allowing you to flank enemies and search for secrets.

Made in bits and pieces over the course of nearly a decade by a single developer on Linux using C/C++, OpenGL, and open-source Quake mapping tools, Ctesiphon's custom engine allows for the game to run reliably on low-spec systems. It's built to withstand large firefights with dozens of enemies, hundreds of blood spatter and bullet impact decals, and piles of giblets and scrap as you blow the enemies apart into clouds of particles and debris.
Ctesiphon has been developed on Linux first and supports virtually all controllers connected to it. On Windows only XInput-compatible controllers are supported natively, but others will work fine with SteamInput enabled. The big exception is for the Steam Deck and Steam Controllers, these won't be natively supported on Linux/SteamOS until after release but in the meantime they should work fine if you play the Windows build by setting compatibility to any version of Proton.

it's 2 hours long thats a bit of a bummer, grab on a sale, it's cute, was made by like 2 ppl i guess and it uses quake code and trenchbroom i think
Ctesiphon is the kind of game where you want to advise it as much as you want to not advise it. For every element it does well, it does an almost equal number of things poorly. It is a really neat looking late 90s throwback that has cool aesthetics, great movement and some reasonable combat, somewhat thrown off by odd sound implementation and really out of whack level design. It may well have the juice for throwback FPS addicts, but everyone else may end up finding it frustrating. As per usual, to be clear Ctesiphon is not too bad. At its core there is a lot to respect about it. For one is the aesthetic and mood. While this may seem like a surface topic to talk about, the look and mood of a game can make the difference between something you stick with or lose interest in before you even try playing it. Aesthetically Ctesiphon feels very 1998 to 2002. It has that late 90s, full 3D with lots of funky lighting effects to it. A popular comparison would be Unreal, but to me it looks and feels more like something made in LithTech such as AvP2 or Shogo. While not too popular an engine, it had some very distinct titles in it, and that kind of throwback sits with you. More impressively is this game is made in its own custom engine, which possibly helps with the render style and mood. Absolutely distinct in this regard. The look ties in with the theme. You are, from what I gathered in the fast (unvoiced) conversations, a bounty hunter who has been tasked with taking down a mercenary group in the city of Ctesiphon. You start out on a sun-kissed beach before moving to a nearby jungle at night and then on to the city and its locales as the game progresses. This takes place over about 6 or so large levels. Despite this, Ctesiphon is surprisingly short. I clocked in 3 hours, and that was with some almost full mission losses where I died close to the end and forgot to quicksave. This shortness can be seen as lack of content, and to a degree that is true. There are very few enemy types to take on, but they are mostly fun to shoot. These range from regular soldiers, odd office worker robots with chainsaw hands, drones that throw grenades at you and a couple of others. In most cases you will be fighting the regular troopers (who have the oddest agro sounds) and chainsaw robots, who are mostly satisfying to take on and shoot. Their AI is a bit dumb, but they gib nicely. What is annoying however are the huge mechs that stomp about the levels. They are, by and large, bullet sponges. You can use regular weapons to take them down, but in most cases you’ll need to find a rocket launcher or gyrojet gun to combat them. While that may sound simple enough, in the early game you frequently end up having to use shotguns and plasma guns on them, and neither are particularly effective against them. Considering the mechs tend to also have other enemies swarming you while this goes on makes the encounters with them frustrating. Thankfully you have two major advantages: the game’s arsenal and the movement. While the arsenal is slightly bloated, the majority of the guns are fun to use. Be it the basic SMG (which has a scope) the shotgun, the plasma gun or even going into the power weapons like the rocket launcher, gyrojet or the absurd water gun (BFG that is far more effective than the name suggests) the guns are fun to shoot and the enemies tend to gib well. Along with that is the movement. While there are not really any gimmicks to speak of, the custom engine with a clear attention to the movement speed and general motion shows the dev clearly knew what they were doing with that. While that may sound wishy-washy, consider good basic movement to car handling: drive a car with bad steering and then compare it to one that has been finely tuned. You notice the difference quickly. Essentially, the general combat and movement Ctesiphon nails! Unfortunately there is a big issue when it comes to the basics; The level design for Ctesiphon feels somewhat scattershot. Some levels are huge and difficult to navigate, then you will have levels with lots side routes that don’t seem to go anywhere. Maybe it was just my poor sense of direction, but sometimes I would miss a switch in places, or forget where a locked door was, leaving me to run around aimlessly for a while. On one hand, the folks who like no hand-holding will like it, and it does reflect some Im-sim design ticks, but I found it irritating when I missed a switch in a corner or a vital item in a location. An example would be on the penultimate level where there was a bridge I needed to raise. After running about the level for about 20 minutes I almost gave up, before diving deep under the water around the level and finding the last area that was only accessible by swimming under the building. Maybe I’m too accustomed to games with visual cues, but I found that quite frustrating. This is the imbalance of Ctesiphon: The combat, aesthetic and movement are stellar, but the level design (especially the flow) and some enemy encounters are annoying as heck. If you are patient, I think Ctesiphon would be a somewhat interesting game, but for the more casual player it will drive you up the wall. Despite these issues, I’d watch out to see what comes next. Ctesiphon feels more like a dress rehearsal than a full title. I’d love to see what the dev cooks up next. For now though, Ctesiphon is a take it or leave it title. Maybe pick it up if you yearn for LithTech titles, but be warned there is some jank contained.

[h1]A lost gem forgotten to ancient past...[/h1] *Disclaimer: game key was provided to me by the dev **I was allowed the full freedom to say anything in my review. Thank you!!** [b]Fans of Half-life, Quake, Doom and many other Old school retro shooters of the golden era will be at home here.[/b] +The movement is fast and frantic, gunplay is snappy and responsive, mechanics and drops are well made/placed, and most importantly, the enemies and levels are well stitched together for satisfying completion. +runs and plays like butter (2 hours in) So far I'm having an absolute blast and each level doesn't feel too long or over stay its welcome. I think based on the quality and game that is present here the price is more than justifiable, especially when putting into account you're supporting a new upcoming passionate indie dev. On sale it would just be a steal. Send love and help them breathe new life into this genre! Seriously, do yourself a damn favor and play this one. A game with great dialogue, story and setting alone is enough to get me hooked. However the games overall feel brought me right back to the intense joy I felt playing all those classic 90's shooters such as Half-life and Doom.
Great game! Enemies are well thought out and keep you on your toes, the levels are pretty too
Ctesiphon - is a cute ,old style shooter. Good: I like the discretion that the game took to look. The characters are nice with their dialog even if some of it escapes my attention due to being told in the middle of the battle. Music is nice ,and shooting is satisfying. The game is short (it's a plus). Maps are well done ,one thinks … The game has some secrets, some easy and some technically evil to find … The bad parts: The plasma weapon could have more power or fire rating. Using it against robots is not always a good choice ,(which might be due to me playing on a high level of difficulty.). And some maps have geometry that can make players stuck forever, but it is rare to find them. Ctesiphon is a good game that I enjoyed playing, 8/10 +with all the beautiful views the game has.
Ctesiphon is a fairly short and underrated hidden gem of a boomer shooter. The weapons pack a nice punch, combat is fast and fluent, the levels are interesting and the soundtrack is really amazing. It does remind me a bit of Ion Fury and Selaco, but it is definitely not on the same level as those two games in any aspect, but it was still quite fun to play through, although it only took me around 2 hours. I do have a few points to criticize: Firstly, there are very few decorative items scattered throughout the levels (except for some cacti), which gives the levels a kind of sterile and empty feel -- decoration is one of the reasons that made the levels of Duke Nukem 3D so much more interesting that those of Doom and modern examples like the aforementioned Ion Fury and Selaco are really good examples of great level decoration. Secondly, the game only offers a handful of enemy types, which get boring pretty quickly. And thirdly, both the final boss fight as well as the ending are pretty anti-climactic -- it's just one of those circle-around-a-bis-ass-boss-and-keep-firing-until-it-falls-over fights with no real challenge and the ending is just two lines of pointless dialog -- an ending with a little more bang would have been nice. In any case, if you like boomer shooters and the screenshots are visually appealing enough for you, then you should give it a try. Finally: I played the game on Linux Mint and it ran flawlessly without any bugs or crashes.
Is good
game looked like it had a kool vibe so thought id check it out and it definetly delivered game ran great and was alot of fun, the levels were varied and interesting with a lot of secrets to find and alternate paths to choose from the world & story had a 80s retro futuristic action movie vibe to it with mechs and mercinarys and super villains on a private island weapons all had an alternate fire and ranged from standerd shotgun/ assault rifles to unique and kool ones like a gyro jet belt fed mini rocket launcher and gause rifle. shooting was good and weapons were usefull campaign was tough but fair and took 5 hrs to run through. would reccomend
[b] Ctesiphon ist ein solider Egoshooter im Retrostyle [/b] +Relativ gute Egoshooter-Mechaniken +Gute Hintergrundmusik +Gute Vertonung -Eine gewöhnungsbedürftige Steuerung (PS4 Controller) Das Spiel gibt zwanghaft vor: R2 = langsam gehen und L2 = in die Hocke gehen. [h3]Ladet mein PS4 Controller-Profil herunter, damit lässt sich das Spiel relativ gut spielen.[/h3]
Nice little shooter. It's not high on graphical fidelity, it's not long, it's not spectacular, but it's fun. Pretty good fun actually. It kinda focuses on what makes a boomer shooter good and skips the rest. You don't have a AAA guy creaking some leather while you run, put blinders on you, talk to you all the time, flashing you often and screaming "IMMERSION!" at you. And I don't miss that guy. Now what the game has on offer are a couple of well designed levels, and while it is still a shooter, half the fun is finding all the secrets... and often it's way easier to find ways to go out of bounds or out of sequence than finding the actual and on occasion supposed secrets. There are also a lot of spots where you'd expect a secret and there is none. That egghunt is certainly a guilty please. So, yeah, it's imperfect good fun with little to complain about.
