Beating Operation Dark Hours is not simply about eliminating enemies; players will need to understand the mechanics of a fight, find a strategy to counter those mechanics, and then execute that strategy. Players will have different roles during the four major boss battles – whether that involves fighting enemies or interacting with the environment – and coordinating as a team is essential to victory.
Communication and healing will be more important than ever as armor kits will be restricted to a maximum of two per player. Your standard skills – like your healing drone and booster hive – will be effective on your entire team, but gear and Specialization Talents will only apply to your sub-group of four Agents. The entire raid is considered a "no respawn" zone, meaning you can't respawn during combat; your only hope will be to be revived by teammates. Reviving works on a token system. At the start of each fight, each player receives a Revive Token that allows them to revive an unconscious teammate during the battle. Each player can revive one teammate per battle, and only one. This does not apply to fallen players who are still able to crawl around, they can be revived normally.
