Discounts
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 3 → 0.86/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 2,402 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.

My coworker is a cousin of one of the devs for this game and she held me at gunpoint to play this game. Emotional scarring aside, I'm glad she did. I love me a good metroid-vania and this one is fantastic AND has a really unique idea for the world the game takes place in. (By "world", I mean sick dog) I absolutely recommend this game to just about anyone!
Another game where a "mixed" recommendation would be perfect. The game is good, the Construct 3 engine is bad. Unplayable (for me) on Steam Deck and has some stuttering on desktop as well. I was using the native Linux build as I couldn't properly run the Windows version. There are also some bugs: sometimes you fall thru platforms, I was able to teleport to non-discovered portals, on one particular boss the button presses sometimes didn't register. It also couldn't work with my 8BitDo controller.

It's very run of the mill. If you've played a Metroidvania before, and have watched Osmosis Jones, you've basically already played this. Negative review because the final boss softlocked and I had to do it again.
Quick Description: -BioGun is a twin stick shooter, metroidvania hybrid that has a bright, vibrant art style and a fun sense of humor. While I enjoyed my first 8ish hrs with this one, I wouldn't say that I was ever blown away. I like that it's made by a small team of passionate game devs. I liked the different weapons, some of the cool abilities, and the bosses are pretty challenging at times. Unfortunately, this game lacks a lot of polish. I ran into about a dozen or so very small bugs. Near hour 7, the game would start lagging like crazy when there was a lot of particle effects on screen. I could have forgiven all of these things, if I didn't run into a game ending bug. I tried to fight a boss 4 times, and all 4 times, the game froze at exactly the half way mark of the fight. The boss has a transformation when you take out half of his health, but no matter what I did, I could never continue the fight. Consensus: -Bottom Shelf Game (Tier 5 and makes up 10% of my reviews). This is a huge bummer b/c I was finally starting to unlock some really cool upgrades and abilities. I was starting to feel really powerful, and then this happened. I see zero reason to continue b/c this is not an optional boss. You have to beat him in order to get the Atomic Drop ability, which allows you to clear pathways to unlock new areas of the map. So, I can't in good conscience recommend this game, unless this is patched up in the future.
A very funny and cool metroidvania. I enjoyed it a lot! I might even try to 100% it someday. (+) Loved the cartoony art style (+) Exploration always felt rewarding (+) Non linear to the right extent (I sequence-break’d twice without even knowing) (+) So many easter eggs (+) Voice acting was very enjoyable. (+) The story and writing was quite funny, I actually laughed out loud (+) Very interesting achievements / challenges (0) Controls can be quite finicky and complicated initially, but you get used to it eventually (-) Does not work well on Steam Deck, the game also tells you that (-) Some bugs that can be quite annoying (I had to restart a few times to fix them) (-) Movement sometimes failed miserably
Even though twin-stick metroidvanias tend to be not my cup of tea as fiddling with one stick is already too much for me, I massively enjoyed completing this one over its 20 hours play time (96%). The game is drawn beautifully if you like these comic-style colourful MV variants and it has lots of fun upgrades, which come early and often. Backtracking is ok, the map is AWESOME, with upgrades allowing you to show secrets and collectables on it. Bosses tended to the difficult in the beginning but not later on, as the game allows you to grind for more health midgame. There are accessibility "cheats" in case difficulty is too much for you (great!), but they disable achievements (not so great). Some achievements for 100% are too grindy for my taste but otherwise this is a great game and an underrated gem. Just a shame the devs do not develop a successor but something completely different. I hope some day there will another MV from you guys! :) Thanks for this one.
Wow!! What a game, indeed worthy of much more attention. Had a blast with it, the overall package is quite a ride. Very much recommended for those who enjoy this type of games. To me it’s up there with the very best, no need to mention their names. BIOGUN it’s a hell of a game 10/10 ⭐️⭐️⭐️⭐️⭐️
