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): 0.14/day in the week to Aug 22 → 0.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

Decent. Nothing super special, but nothing bad. If you want another Survivor style game to play, try it out.
There is an extreme lack of variety in weapons/abilities compared to most games of this genre which makes the gameplay too repetitive. Combined with how lackluster the upgrades are, it makes the progression system too tedious and boring. At least it's really cheap.
Fun roguelite with decent metaprogression, hoping to see it grow into a game i can play for many more hours

For a vampire survivors in a sci fi setting, its actually a good game, wished it at hand lightsaber tho for a more melee style of combat
i am surprise that there is no discord
April 4th 2023 patch 0.7.2 game has become unplayable for to long with dev/s not posting a hotfix for the infinite loading bug that prevents game play. will be requesting refund as I can not play this game due to design. (was turned down by Valve asked to play next patch and ask for refund if product still wasn't working) May 23 update 0.7.4 This did in fact fix the recent game-play breaking bug that was effecting me.
I didn't hate it, but it's very cheaply put together and has numerous flaws. Just a basic Survivors clone with a lot of grinding.
Plenty of grinding, nicely presented. Top tip - read all the research options (there are 4 or 5 tabs) - some are easy to achieve early on and help speed your progression significantly.

Basic survivors game, but pretty good for what it is - especially for the price.
