Dead by Daylight. An absolute sleeper hit. You play either a supernatural Killer trying to stop a team of 4 Survivors from completing objectives and escaping - or one of the Survivors trying to avoid the Killer, complete the objectives, and escape. The neat thing is that there's NO in-game chat, so it's 4 random people who don't know each other, figuring out how to work together and help each other out. (There is a post-game text chat, where people can cry and whine about it... LOL).
The graphics are amazing, the gameplay is smooth, there's a TON of variety and replay value, and they have a lineup of licensed Killers from popular franchises and arch-concepts - Chucky, Michael Myers, Dracula, Vecna, Xenomorph, Huntress, Trapper, Doctor - each with their unique gameplay, tactics, and strategy. Multiply that by the dozens of "Perks" and "Add-On" items that twist the gameplay in interesting ways, and you have literally tens of thousands of variations on the gameplay. From stealthy and surprising, to brutally overwhelming.
I honestly used to be addicted to team-RTSs like Age of Empires and World of Tanks, but now this game has 100% of my attention. It's THAT good.
