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 5 → 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.
About
Tactical retrofuturistic strategy game. A computer virus has infiltrated the "Stargazer" research complex. Most of the robotic units are controlled by the virus. Lead a squad of 4 prototypes on a mission to defend complex mainframe. You'll have to repel assaults, destroy unit fabricators, download valuable data, clear infected nodes, and do more on your way to the deepest parts of the complex. Work with item limitations and drawbacks to build powerful combinations. Destroy your enemies with diverse tactics: overheat them, melt with corrosion, absorb damage, and return fire. But don't rely on a single strategy too much - enemies might have a way to counter it. But above everything else: defend the Mainframe!
* RETRO STYLE: Graphics, inspired by 80s terminal PC with hybrid synthwave soundtrack.
* DIVERSE TACTICS: Cook enemy robots to death, bury them under your bullets, eliminate with a single powerful shot, or render your opponents useless with debuffs - this game is designed with a lot of viable strategies in mind.
* BUILD YOUR SQUAD: Similar to how in card games you have to build your deck, in Mainframe Defenders you have to combine different items with unique abilities, to create an unstoppable squad. Work with item drawbacks or double down on them, creating flawed, yet powerful build!
* UNIQUE ENEMIES: Enemy squad won't sit idle, though. Each unit has its own role in the squad and designed to counter certain strategies. Pick your targets wisely, or you will lose.
* PROCEDURAL LEVELS: Hand-made rooms are combined with procedural generation to create random levels. Missions have differing objectives, combined with unique mission conditions. Will you accept the challenge or avoid the unknown and risk falling behind?
* PROGRESSION SYSTEM: Victory or defeat, the game is not over yet! Unlock new units, each with a unique set of upgrades and load-outs. Unlock new items to bolster your new strategies.

Very slow and painful. Maybe it gets more interesting later but my usually long patience was short here. If this game catches your eye but you don't feel good about it, maybe try Cogmind or another traditional roguelike.

A solid and enjoyable experience overall.

Not my kind of game
Enjoyed playing this one quite a bit.
— Несучка? Подходит игрок к роботу выбрать снаряжение: — Ствол хороший? — Ещё какой! Первая пушка в мейнфрейме. Урон, дальность, поджиг. — Беру. — Только патронов к ней нет. И слота под неё нет. И робот под неё не подходит.
A completely flat experience. There is no hook, no charm, and absolutely zero reason to keep coming back to it.
Прикольная игра, еле пытался пройти легкую миссию. Потом пошел в обычную и победил.
Не моя история.
