This game is the bomb. It's the game that is actually stealing me from TF2, and I enjoy it to all heck. If you wanna know what it's all about, read the next paragraph. If you already know, skip it pweas.

You basically play as either a Killer or 1 out of 4 survivors, where their are many to choose from. As a survivor, in order to win, you have to, well, survive! Fix up generators and evade the killer by vaulting windows to set some distance between you two and setting down pallets on their faces to block their path. Fixing up gens all the gens (the amount depending on the amount of survivors their are) will allow you to open a gate, so you can finally escape the hell your character is in! As for the killer, try to pick a killer best suiting your play style (Mobility? Chainsaw Boi. Stealth? Black Bing-Bong of death. Area-control? Big Boy Trapper. etc) and game end (family friendly) as much survivors as you can as well as stopping them from repairing generators. 

What makes me like this game so much is that though the description I gave was a bit lean, the main reason why I like both TF2 and Dead By Daylight is because of variety of play style.  Though when you play a Killer, you can only play by their general play style, certain perks and add-ons (types of items in-game that can change or add things to how you play) can ultimately change the way you play the game, Killer or Survivor. The graphics of the game are pretty slick (although I can't enjoy them on my computer cause my computer runs on lemons) , and looks like a game that would be worth 40$!
