A new trailer from F.E.A.R. 3 explains the scoring system in the first-person shooter sequel in development at Day 1 Studios. Here's word on how this works: "Players can choose to work together while playing co-op to achieve the best group score, or work separately, secretly stealing from and backstabbing each other for kills and points. One way that gamers will be able to rack up the points is through the game’s 'challenge system' which rewards players for approaching the game with different gameplay styles."
