Subterfuge Weapons Assessment Program, an obvious backronym for S.W.A.P., takes the first person shooter genre and removes the whole "damage" mechanic. Basically, shooting an opponent will have your character "exchange bodies". The point is apparently to prevent the enemy from delivering a payload to your base or put them into situations where they will kill themselves once they are at your position.

While I have yet to play the game, it is free. No micro-transactions, DLC, or subscriptions. They are using this project to gauge interest for a full, Unreal Engine release. It has an interesting art style, reminiscent of Unreal Tournament (1999) or the original Tribes. It could be worth a download, especially if you like old-fashioned arena shooters and unusual game mechanics.

Those are two genres which do not get mixed a lot…
