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 10 → 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.

Reviews
Great shooter. I love the artstyle. Weapons are very original. And I like the idea of heaving basic weapons with unlimited ammo. All weapons feel great. Mobs are properly designed and they work great in every level. And the level design is very neat as well. Eternal harvest is a great update for the game and keeps the replayability high. The way the levels change after a wave while playing is done really well and doesn't glitch or bug at all. Play this shooter if you're into modern boomer shooters.
