>>715234065 (OP)Blacklight Retribution was a lot of fun even if the monetization shat the bed pretty hard. It was an FPS with the central gimmick of everyone having the ability to turn on wallhack if you lower your gun.
There were lots of items to play cute mind games with your opponents: decoys that only show up in wallhack vision or only without it, placeable jammers projecting a bubble that makes you invisible in wallhack vision but not without it, cloaking that doesn't make you invisible in wallhack vision, etc.
That's on top of other fun stuff like kitbashing your guns or the ability to buy mechs with points you earn for kills/objectives. You had to counter those with special weapons, like RPGs or a flamethrower that could "cook" the mech, killing the pilot and letting you steal it.
