This trailer from Atlas Reactor shows off how the simultaneous turn-based system will work in Trion Words' upcoming tactical shooter. Here's a brief outline of the system:

In Atlas Reactor, turns are divided into two modes: Decision mode, where players choose their actions, and Resolution Mode, where players watch their decisions play out. Each turn is broken into four distinct phases, which always proceed in the same order - Prep, Dash, Blast and Move - with each phase coinciding with specific gameplay actions. By working together as a team and predicting and understanding enemy actions and phases, players must devise the best strategy to put themselves one step ahead of the competition and achieve victory.
