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.
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.

Top demais! Gostei de cada momento jogando
Really Love this game reminds me of a Super Contra or Midnight Resistance game on steroids! Hell Yea!!!
Great little gem, all the better for being a very playable contra clone with a health bar. Needs patching it so that a little health is lost when you fall down a hole rather than a whole life. My only gripe with it.

Bio Lab Wars is a $1 Contra clone. It's not bad either. Not many games can say they have a chicken that shoots lasers as a sub weapon.
Um dos melhores contra like já feitos, dificuldade na medida, muito divertido e fluído. Ficou ainda melhor com as atualizações.

un juego entretenido estilo Contra muy retro.
I definitely have to recommend Biolab Wars! 2ndBoss managed to capture the look and feel of games like Contra, and just stuck to the basics. The gameplay is spot on, the visuals are fantastic and the soundtrack complements the on screen action perfectly. I had a blast playing through this and if you are a fan of run and gun games I'm sure you will too.
É um bom jogo para matar aquela nostalgia de jogos antigos ou apresentar a crianças e inexperientes em jogos antigos a estética e gameplay de jogos antigos sem ser tão punitivo, uma boa entrada. É um jogo acessível e simples que até é desafiador em vários momentos, mas para alguém mais experiente pode ser desinteressante e monótono o level design (embora talvez isso seja só comigo, pois não cresci com Contra que é a inspiração principal, e sim Mega Man) e bosses também (apesar do último ter sido bem legal, o resto é muito previsível e simples). Minha única decepção grande é todos os personagens serem apenas uma mudança de skin, teria sido muito bacana se cada personagem tivesse sua particularidade ao controlar.
I was scrolling through some of the sales on 2D side scrollers and I saw this one for a $1.19 and I was like why not. It’s basically just a dollar. If it sucks it sucks. The intro is 20 seconds and basically can be summed up to something happened, and send in the mercenaries. It gets right to the game which I like. There are 4 playable characters. All of which have a cool 80s aesthetic. You have your normal male and female action hero types. A Labrador retriever in a mech suit which is obviously what I went with. Lastly a jackolantern themed action hero named Jack. They all play the same so it is just for aesthetic. The game plays similar to Castlevania 1 or 3 meets Contra. It’s a forward moving run and gun with some fun boss fights. I thought the music was decent. The gameplay is fun and engaging. Some of the jumping is a little off but it is mostly when jumping between ropes that it becomes noticeable. The powerups are fun except for the spread. The spread look like it belongs in a game like 1942. You can get sidekick characters like a kitty with a jet pack who shoots at a downward angle and a chicken who floats and shoots forward. Both are vital to certain portions of the game and add a fun cuteness. The levels are broke up similar to Blazing Chrome where once you beat a level you can select it if you die. The game is mildly challenging but not that hard. Most people familiar with this genre shouldn’t have an issue with it. You can probably run through the whole game in 30 minutes to an hour depending on skill. Honestly this game is a lot of fun and I would recommend it. It is made by only three people which is awesome to see.
