NEW FEATURES
New Class: Techmarine
We are introducing a new playable class: the Techmarine! This mighty technician specialises in crowd control and area defense, handling multiple combat tasks simultaneously. This is primarily possible with his Servo-Gun ability.

Furthermore, the Servo-Gun allows executing Gun Strikes without interrupting other actions.
