Key Mechanics & Features

Here are the core gameplay elements and features:

Feature Description
Tower Units (“Brainrots”) You acquire and deploy various brainrot creatures as your defensive units. Each unit has unique attack patterns, strengths, and roles (e.g. DPS, support, area damage).
Upgrades & Traits You can upgrade your towers—boosting damage, range, special effects—and sometimes assign special traits or enhancements to make them better in later waves.
Currency & Resources You earn in-game money or similar currency by defeating enemies. Also, Gems (or premium currency) are a big part for summoning or unlocking rarer units.
Wave / Difficulty Scaling As you progress, waves get harder, requiring better unit combinations, good placement, and strategic upgrades.
Unit Roles / Tiering Units are often classified into roles (DPS, economy/farm, support) and also ranked in tiers (S, A, B, etc.). Guides and community tier lists help players choose optimal picks. Destructoid+1
Redeemable Codes To get boosts, Gems, or special rewards, the game supports redeemable promo codes (which we discussed earlier).

Where devs and community post new codes

Community sites & code aggregators (Lionjek, ProGameGuides, Gamerant, TheGamer, Roblox Den, Destructoid) — good for cross-checks.

Content creators / X (Twitter) / YouTube shorts — creators often share one-time codes or early leaks; check short videos and X posts for immediate codes (e.g., creators posting new 500 Gems codes via shorts/X).
