May 21, 2026 - Eight weeks ago, CRUNCHFEST and GROLAF launched CODEX MORTIS into Steam Early Access. Today the game sits at Very Positive on Steam with over 80% of reviews recommending it, fifteen community patches shipped, and a sixteenth landing right now: the Mutations Update, the largest content drop since launch. To celebrate, CODEX MORTIS is 20% off on Steam.
[<<MUTATIONS UPDATE TRAILER>>]
The main addition is Mutations - 249 of them, across 31 spells. These aren't damage bumps. Each Mutation rewrites how a spell works: a single-target bone spear becomes a 360° nova, a circular AoE becomes a four-armed cross, a slow-aura banner swaps into a burn DoT, summons turn into glass-cannon swarms. Players already deep in theorycrafting get a second axis to push on; newcomers get clearer routes into the deeper end of the system. The wrong build still flops - the right one goes somewhere it couldn't go yesterday.
The level-up flow is rebuilt around it too. Picks now reward composition over spam, which means the same eight levels can play eight different ways depending on the loadout you brought in.
And it all moves. Every character and every enemy in CODEX MORTIS is fully animated - the necromancer's cast, the shamble of the restless dead, every summon and swarm that fills the screen. The chaos reads as cleanly as it plays.
