Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 29 → 0/day in the week after.
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.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

STORY
Inspired by the "hero" shooters of the late 90s such as Duke Nukem, Blake Stone, and Wolfenstein 3D, DOSMan: Space Aliens in Space is a retro FPS game where players take on the role of the titular, DOSMan.
Aliens have invaded Planet DOS, and are wreaking havoc upon the population. It’s up to DOSMan and a colorful cast of hilariously incompetent characters to beat them back and restore order to the once-peaceful planet.

"DOSMan: Space Aliens in Space!" is another fun, bite-sized boomer shooter from this publisher. In "DOSMan: Space Aliens in Space!" you shoot aliens that have invaded the planet, and they stole one singular chick. She has big boobs, you save her at the end (thank god). "DOSMan: Space Aliens in Space!" gives you a standard array of weapons, and each weapon is represented with lovely sprites. Even the enemies have received the lovely sprite treatment. My biggest complaint about "DOSMan: Space Aliens in Space!" is the enemy-ammo ratio; you will not have enough ammo for every enemy (unless you put the knife to good use). Also, while the shotgun looks and sounds awesome, its efficacy is poor. ROF is king, and its slow fire along with weak damage makes it a last-resort weapon. "DOSMan: Space Aliens in Space!" is fun, has a lovely artstyle, and some very light but endearing voice acting. If you like these things, you should definitely buy "DOSMan: Space Aliens in Space!".
This is a great casual entry in its genre with vibrant visuals, simple but satisfying gameplay, and plenty of old school charm. It is also very affordable and comes in a lot of bundles...so there's really not too much going against picking this one up and trying it out, especially if you see it on sale. I do see a trend with a quick glance at the other reviews regarding the length. Personally, I prefer shorter experiences more often than not, so The game only taking an hour, hour and half or so (depending on how much you explore or start sequences over) is pretty reasonable to me. I didn't die [i]too much,[/i] but I will highly recommend using the save feature to prevent having to replay lengthier sections. If you're very familiar with this genre, you're going to see a lot of familiar tropes in a fairly colorful packaging. For everyone else, this is a nice entry to dip your toes into the genre with.
What even IS a DOSman? DOSman: Space Aliens is Space! is a Retro FPS game developed and published by DOSman Games, Running on the EFPSE engine. It follows the titular DOSMan as alien invaders have invaded his home planet of planet DOS and does the most logical solution as a Retro FPS Protagonist. Shooting everything that moves with some hi-tech weaponry to get the job done. While it does follow kinda the same route as other DOSman developed games up to this point, having a basic scope of the game throughout the whole thing. There's a bunch of little additions that the previous games didn't have that put it just above the previous games released. Gameplay of DOSman is that basic Retro FPS gameplay loop. Level to Level, Filled with enemies, maybe keys to collect to progress, and secrets to find. This is going to sound pretty familiar if you've played DOSman's other developed and published games using EFPSE. However, this is the first game I've seen so far to implement world building inside of the game itself, not just intermediate cutscenes or dialog that you can barely hear. But with actual levels dedicated just to elaborate on the simple but charming plot. This is also the first DOSman developed game on Steam to focus on ranged weaponry primarily, featuring a pistol, shotgun, a rapid fire weapon, and an explosive. This shift to guns is pretty obvious once you've seen the highly increased enemy count. There's even a clever usage of the breakable props gimmick that spawns a enemy, which isn't too extreme but makes you thinking a tad bit more on where your bullets are landing. There are some points where ammo becomes a tad too stingy but nothing ball breakingly hard. Stylewise, DOSMan got that "DOS game"-esque artstyle back in full force. It works especially well here given the combination of EFPSE's 90 degree wall structure for building levels AND the fact the game has a Space theme, making it have similar vibes to something like Blake Stone. There's also a focus more on bigger, bolder pixels than normal, really helps to give that "retro space" FPS vibe. Honestly the most the game could have done a bit more is just adding more details to some of the other levels, since it does feel a bit more barren than the other DOSman developed games. Overall, DOSMan: Space Aliens in Space! another great bite-sized FPS from DOSman games and absolutely a step-up from previous developed titles. As per usual there's definitely room to criticize the length and the issues from the limitations of the EFPSE but once again given the low base price and even lower on sale, it's perfect to just pop in to kill time for a afternoon. Although unlike other DOSMan games other than maybe Flash of the Blade X, this is the first game developed from them that has a decent floor for a potential sequel. Hilariously, kinda like Blake Stone, whatever that is.
[url=https://store.steampowered.com/curator/45346629/]Fun Retro games curator review: 6/10[/url]. A retro FPS, situated roughly in 1992, halfway between Wolfenstein 3D and Doom in terms of tech. Thematically it feels like an homage to Blake Stone if anyone can remember that. Level design is decent. The rest of it is just so so but somehow it manages to be fun, in part because it does not overstay its welcome at all. But if you didn’t live through the era this is referencing you probably won’t enjoy it. Difficulty is fairly light and mostly comes down to limited ammo. Probably the ideal time for this is when you’re feeling like a break from something deep, heavy, and/or difficult in your gaming library. Lets you save at any point in the game. No game pad support but plays fine with steam input.
就挺平庸的,而且很短,无中文,流程一个小时左右。
Nice and short boomer shooter style FPS. I enjoyed the retro throwback, reminds me of Blake Stone.
This feels like it was installed from a cereal box.
