I'm going to start up a discussion regarding strategy in this game;

In my opinion, the most effective way to consistently win in this game revolves heavily around letting being extremely stealthy & opportunistic, in which the main premise of the tactic is to not compromise your position / take damage and only engage opponents if they engage you first, unless you are certain you'll win the engagement.

Optimally, you'd only need to take one engagement in the entire match, and that's with the final opponent left. The final opponent will most likely at a serious disadvantage at this stage, their position will almost certainly be compromised, along with the possibility of their health and shields being low or depleted. This sets you up perfectly to have a very high chance of winning the entire game, achieved by superior positioning / strategy instead of relying on mechanical skill and raw aim.
