What Mechabellum 2.0 added

The official announcement presents 2.0 as a major release update. Its headline additions are Star Expedition, a new unit called Centurion, more Reinforcement Cards, Techs and Specialists, and a Free Edition on Steam.

The announcement dates the Free Edition and 2.0 launch to September 22, 2026. This article records that dated announcement; it does not claim that every launch detail has remained unchanged after subsequent updates.

Star Expedition: solo and co-op mode

The announcement describes Star Expedition as a mode combining roguelite progression with asynchronous battles. It can be played solo or with one other player.

The release post describes expeditions across nine planets, changing units, Techs and reinforcements, mirrored builds from other players, and rewards that can influence later runs. Treat this as the launch description, not a complete rules manual.

Centurion: the new unit

Centurion is the new mech named in the 2.0 announcement. The post describes rifle attacks at different ranges and a melee mode, alongside a set of exclusive Techs.

This overview does not rank Centurion or recommend a build. Exact Tech values, interactions and matchup performance should be checked against current in-game tooltips and patch notes before publishing strategy advice.

Free Edition and Battle Contracts

The announcement says the Free Edition became available on Steam with the September 22 launch and that player progress carries over when upgrading. The launch post also lists limits involving public chat, Star Expedition storage, cosmetic rewards and Tech Point progression; check the current Steam page for terms that may have changed.

The same post introduces Standard and Elite Battle Contracts. It says Season 9 rewards move away from Combat Power gating and are earned through the new contract system across game modes. This is a summary of the announcement, not an independent review of current reward availability.

What this page does not verify

This page does not establish a current tier list, the best unit counters, competitive MMR distribution, or the strongest compositions. An official release announcement cannot verify those player decisions by itself.

Before using a unit or build recommendation, check its publication date and whether its gameplay evidence matches the live version. Videos made on the 2.0 test server are not treated as proof of post-launch balance.
