Choose by what carries your run
| Your run | Consider | Reason |
|---|---|---|
| Strong weapon core | Mecha | Choose reinforcement stats for the weapon plan. |
| Strong passive item package | Mutation | Random copied effects can develop that package. |
| Dying before scaling | Immediate survival | An unfinished scaling plan cannot rescue a dead run. |
This is our editorial framework based on the developer’s Evolution explanation ↗ (opens in a new tab). It is not a measured ranking.
Follow the drops and watch the hazards
Mecha parts feed weapon reinforcement. The launch post also describes dismantling mecha weapons for additional parts. Mutation copies item effects randomly. Inspect the actual result before building your next shop decision around it.
Mecha enemies introduce lasers and slowing oil. Mutant enemies spread acid. Leave an exit lane instead of crossing a puddle to collect every drop. Directed upgrades can be easier to plan around, while random copies require checking what the run actually gained.
Read the branch before copying a build
The 6 November beta-0 patch changed Mutation scaling and Mecha reinforcement growth. The 10 November 1.2.0.2.beta-1 patch further reduces mechanized weapon damage from +5% to +3% per mecha power point (+108% at eight mechanizations, previously +180%) and removes extra piercing and bounces from mechanization. Budget crowd coverage separately. These changes apply to the optional Steam beta. Steam Library → Brotato → Properties → Betas shows participation. 10 November beta-1 notes ↗ (opens in a new tab)
Inspect Mutation results on beta-1
Each mutation now puts its -1 Evolution on the Tumor. An item becomes mutant when it loses a negative modifier, and duplicate Tumor effects merge into one line. Mutation Fruit base drop chance rises from 3% to 4%, then falls by one percentage point every ten waves from wave 30, to a minimum of 1%. Inspect the Tumor when checking what a mutation changed.

Make the next shop decision
If you lack damage, compare an immediate weapon upgrade with reinforcement. If collection is killing you, buy enough movement or defense to reach the next wave. With Mutation, inspect copied effects rather than assuming the best passive was selected. Reassess when the actual build changes.
