For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,419 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.

Snake Logan is a top-secret operative for the CIA ordered to complete missions that others would regard as suicidal. One day, Snake is called into headquarters and briefed on a situation that has arisen in Metro City.
It seems that thousands of monster-like creatures are on a rampage of destruction through the city. Many thousands have already died, and Metro has declared martial law just before losing all communications. Right before the city was overrun, authorities received a message from a man calling himself Dr. Mangle. He stated that Metro is to be an example of what will happen to the rest of the world unless all factions of government comply with his wishes.
Snake is ordered to take a plane, fly recon over the city and then return. While circling over the area, he is suddenly attacked by some kind of laser weapon, and the plane loses engine power! He's forced to make an emergency landing and explore the ravaged city on foot. It's now up to Snake - and you! - to save any survivors, find the source of this destruction, and stop Dr. Mangle.

Another remake of a classic DOS game from Appogee. BIO-Menace. I remember when I was kid when I found the shareware episode and thought “Hey, this has the same menu as Commander Keen 4”. Yeah, that was my core memory of this game from my childhood, my first experience to games using the same engine. But why would anyone buy this remaster if the game is freeware. 1: A new episode with some bonus levels. 2: A level editor to make your own levels. 3: Customisable UI and the option for the old graphics is always welcome . And 4: some major quality of life improvements. Speaking of those QOL improvements, they are pretty basic but they make the game more enjoyable. Unlimited lives. More health in normal mode. Some dead ends no longer being dead ends. But the most notable is being able to change your ammo and grenades. This alone improves the game since in the original, you can only use the strongest bullets and grenades til they run out. Now how was that a problem? The strongest grenades are landmines and they are more situational than the other grenades. Of course not everything was improved with the snake still having annoying projectiles or those electric ball shooters still shoot at random directions. And that’s about it. Not much to say about gameplay. Just explore levels looking for keys til you reach the end, kind of like Commander Keen only more shooting and some switch puzzles that the new episode is aware stopped appearing after episode 2. Speaking of episode 4, not much was added besides the well made levels. Just some new key types, two new bosses and used the bees from an Episode 2 trap into a normal enemy. Oh and a low gravity level I do want to talk about the odd tone this game has. At the start of Episode 1 had an opening level with several dead bodies lying in the streets. And the enemies are cute little purple slug things and green Barneys with mohawks. Then the next level has this oddly upbeat tune while you fight fire demons and the level after is a park and the OST for that is f-ing menacing. And while that’s just as an adult overthinking some minor detail that doesn’t matter and that was all over games of that time. Can I at least say how out of place Skullman was. Like all the enemies and bosses are these mutated animals and robots and then in the middle of episode 1, this giant blue demon who appears to collect bones shows up and dies with no explanation besides some graffiti. Still I’m just nitpicking at this point. This is a well made remaster and if you never played Biomenace before, play this version. 8/10

I remember playing the first chapter of this game in the early to mid 90s (never bought the second and third chapters). I saw this remastered version and gave it a whirl. The devs did a solid job with Biomenace in remastering it, and the added chapter is great too (especially the music). The options to change the UI of the game are easy from the menu, and you can, with a single button, swap between the remastered graphics and the original 1993 version. Highly recommend if you're looking for old school MS-DOS games to play on modern systems.
I really like this game. I never played it before in the 90s (although I owned a PC). Whoever likes retrogames should give Biomenace Remastered a try. The game save feature makes this game easier for casual gamers, as you can save and reload at difficult parts. Just finished the game. Episode 4 (the new one) is even better than the original episodes!
