Base-BuildingTower DefenseSurvival
$29.99 ~45 hr median co-op complexity: moderate 90.4% of 24k
The Squirrel's verdictWhere Evil Genius 2 asks you to scheme and defend at a measured pace, Riftbreaker keeps you under near-constant attack: you build outposts on an alien planet, research technologies, and fend off waves of enemies in real time. The base-building and tech-tree progression will feel familiar, but the tempo is relentless rather than methodical. Co-op is supported, and the Steam rating sits at Very Positive.
Not for you if you want to pause and carefully plan every placement; reviewers describe attacks as too frequent to allow deliberate base design.

The Squirrel's verdictTactical squad survival with RPG unit progression is what Chromosome Evil 2 delivers: scavenge a city, level your soldiers, and race against timers that punish delay. Base construction is absent. Reviewers praise the strategic depth and branching consequences while flagging rough presentation — characters can slide mid-combat and the skill review interface is missing. Median playtime is 23.9 hours.
Not for you if you want a polished interface or a base-management layer; reviewers report sliding characters and no way to review trained skills.

$6.99 ~34.8 hr median no co-op complexity: moderate 80.7% of 2k
The Squirrel's verdictDemon-apocalypse survival replaces evil-lair management here: your survivors scavenge randomly generated worlds while you maintain a home base and push through research gates. Combat is the central loop rather than an occasional intrusion, and reviews flag it as the game's most divisive element. At a median of 34.8 hours and a Very Positive rating, it offers more systemic depth than Evil Genius 2 delivered.
Not for you if you want lair theming and humor over demon-survival combat, or dislike research gates that enforce a fixed build order.

$14.99 ~11.6 hr median no co-op 82.5% of 355
The Squirrel's verdictSquad-based extraction with gear progression and escalating zombie waves is Chromosome Evil's core offer: outfit soldiers, loot abandoned maps, and escape before the hordes overwhelm you. There is no base to build or manage. Controls are a recurring complaint — unit pathing fails often, and characters stop responding mid-order. A two-person indie team made it, and play runs about 11.6 hours.
Not for you if you want a base-builder, reliable unit controls, or text readable at higher resolutions.

The Squirrel's verdictRogue AI Simulator puts you in charge of a single facility with a randomized layout, managing human test subjects as resources while running hacking minigames and plotting your own escape. It shares the villain-in-charge fantasy and subordinate-management loop with Evil Genius 2 but replaces the global map and story missions with a tighter roguelike structure. Median playtime runs 14.2 hours.
Not for you if you want a sprawling world map, scripted story missions, or a base layout you can plan rather than inherit randomly.

Base-BuildingCity BuilderResource Management
$24.99 ~22.9 hr median no co-op complexity: moderate 75.5% of 715
The Squirrel's verdictExogate Initiative runs the same base-management loop of staffing rooms, queuing research, and dispatching agents, but frames it around Stargate-style interdimensional exploration. Your operatives travel through a gate to other worlds while you manage the home base remotely; those worlds are never shown directly. Reviews document AI pathing bugs and stuck-task loops that were present in early access and remain in the released build.
Not for you if you want to see the alien worlds your agents explore, or have low tolerance for AI pathing bugs and task-loop failures.

CrimeBase-BuildingResource Management
$19.99 ~7 hr median no co-op complexity: light 70% of 2k
The Squirrel's verdictBasement shares the core loop Evil Genius 2 built on: managing a base with limited build slots, directing production chains, and expanding a criminal operation room by room under mission pressure. It trades the spy-thriller lair for a drug-production setup with a stricter, more punishing campaign that demands precise action order. At around 7 hours of play, it is a much shorter commitment than a full base-builder campaign.
Not for you if you want a long campaign, co-op play, or a base-builder that tolerates experimentation instead of punishing wrong moves.
