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): 0.43/day in the week to Aug 25 → 0.57/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.

Extremely repetetive, even the campaign. And holy crap there is so much AI slop in this game...
This is actually a fun game BUT it uses Ai generated content. The generated Ai voices are so annoying I requested a refund. It is so sad because if this game cut the Ai generated content and just had the base game I would have not only thumbed it up but would have happily paid £10. Instead I requested a refund (of £5) due to the horrendously annoying Ai cutscenes and voices. Such a pity.

I've played for 7.5 hours and this is it. There is no more to the game other than a slightly different 5 minute mission on repeat. Has a good premise that is really badly implemented along with questionable AI use.
AI slop.
pretty much what all the bad reviews are saying; starts strong but gets repetitive. resource and reward also feel like i work too hard to get too little. after the first few hours, the juice ain't worth the squeeze on this one. here's hoping i get my money back.
While the core mechanics are genuinely impressive and offer a satisfying tactical foundation, the experience suffers from a lack of mission variety that makes long sessions feel like a chore. It’s a fun, engaging distraction in short bursts, but the repetitive nature of the gameplay makes it hard to recommend at full price; definitely wait for a sale.
Its okay for a time, but its too repetitive
This game starts off as a fun horde-fighting game, but i might have made a mistake by doing too many side-missions, for of those there are MANY. The story itself is rather short and the story missions are the most unique in terms of layout and gameplay. So it seems they filled out the rest of the game by giving the player 200+ sidemissions that they can choose to do. I dont know how many i did, but the mistake was absolutely doing too many side missions, it started to get too grindy after a while and made me lose interest in the game because of it, after my now 33 hours ill probably never play it again. It is fun though, if you dont overdo it. You place turrets and a few hero characters out on the map that you can move around to help out in various ways of taking care of the horde that attacks your buildings or movable units (pending on mission type). During the missions you get XP that when you level up survivors-like style get to choose an upgrade (choose 1 of 3). At first this system is good, but the more you play the more restricted the system feels and you cant get any upgrades for this outside the missions to help you out, like at all, every mission gives you around 10 or so upgrades (maybe more) and its like that no matter the difficulty you choose, so eventually you just feel stuck in the same loop you had from the start of the game. Some of the upgrades you get from leveling up during mission is get 1 more option per level up, or more xp per kill or more xp per drill and so on, and i feel like those things shouldve been upgrades you could work towards outside of missions, but instead the system stagnates, gets stiff and non progressive. Again, i might have done too many sidemissions so this got extremely apparent for me. overall, my enjoyment score for this game is about 71% I'll probably never play the game again. Also, some missions want you to survive for 15 minutes (on hard) but by holding spacebar down you can shave that down to 7.5 min (i think it doubles speed), anyway, these missions really hammer in that the XP system was made for about 15 minutes or so of gameplay at most, post 15 the xp gain slows down so much that it takes almost 10 minutes in between each level up (again, hold spacebar to shave the time down). Even if they did patch in an upgrade system for how many choices per level you get and xp gain, ill still probably never play it again.
Do NPCs in this trash ever shut up?
