I Am Plague: A Horde That Thinks as One
Rats as protagonists do not get enough spotlight. I Am Plague fixes that by putting you in command of a single will that moves thousands of rodents through the winding underbelly of a grand capital. It is an incremental roguelite built around automatic combat and heavy buildcraft. You do not twitch the sword yourself. You design the swarm, pick mutations, and watch the chaos unfold.
The pitch is pleasingly brutal: every run, your horde starts fragile and needs to eat to grow. Die, return to the lair, spend your spoils, and unlock a stronger baseline for the next push. It is the sort of loop that rewards patience, experimentation, and a taste for monstrous combinations.
Swarm Combat, Mutations, and Synergies
Combat runs itself. The interesting part is the decisions you bring to the battlefield. On each floor you choose one of three mutations, buy more at shops, and stack repeats to amplify a favorite effect. Mutations come in multiple rarity tiers and combine in ways that can swing a run from hopeless to unstoppable.
Beyond mutations you can upgrade core stats like strength, attack speed, health, and defense. There are also modifiers for critical hits, evasion, and regeneration. The build you assemble before a fight shapes how the horde behaves in automated encounters. It makes picking between an aggressive, glass cannon swarm and a slow, tanky tide an engaging tradeoff.
The game keeps tension in its choices. At every fork you weigh the danger of a route against its rewards. Will you press on for better mutations or retreat to consolidate your gains?
Permanent Growth With Flesh and Bones
Progression is roguelite rather than purely ephemeral. Currency gathered in the fortress, notably flesh and skulls, is spent back in your lair on two persistent trees: the Tree of Flesh and the Tree of Bones. These provide permanent boosts to base stats and unlock new mutations that can appear in future runs.
That means your first ascent may end quickly, but it is meaningful. Each failure adds options, raw power, or mutation variety for the next attempt. The permanence is tuned to let you shape long-term strategy while still making each run feel fresh.
A Fortress of Secrets and Rising Threats
Narratively the game leans into atmosphere. For centuries the colony grows in darkness and now seeks the surface. Along the way you face soldiers, priests, alchemists, mechanical constructs, parasites, monsters, and even angels. As the horde climbs it uncovers fragments of memories, foreign voices, and the uneasy suggestion that the destiny it follows may not be purely destructive.
Design-wise the developers promise more than 200 dungeon floors, 50 plus mutations, increasing enemy variety, shops, text-based events, branching routes, and progressively dangerous bosses. The further you climb, the stranger the fortress becomes and the more people recognize the horde as something believed dead long ago.
Why I Am Plague Could Hook You
If you like build-driven roguelites that reward creative combinations and slow, permanent power growth, I Am Plague looks like a neat twist on the formula. Automatic combat keeps the focus on choices and synergy rather than mechanical skill, and the rat-horde fantasy gives it a distinctive identity. The blend of progression, mutation stacking, and a creeping, ambiguous story undercuts any cute vibes with a steady creep toward something bigger.
Pick a mutation, watch the swarm, and then die gloriously. The next run will feel just a bit more dangerous for everyone above.
