It’s that time of the year again where we carve pumpkins, buy sexy costumes, and kill zombie robots. Blizzard’s titanic first person shooter, Overwatch has officially started it’s Halloween event. Featured above, you can view a trailer introducing the game’s new content.

Running now until November 1st, players will have the chance to one of the spooky Halloween skins for some of their favorite heroes. 12 heroes total will have special costumes, and there will also be plenty of unique voice lines and taunts for the players to unlock.

Along with the new unlockables, there is also a new Brawl for the players to participate in. Four players must face off against the undead Omnic armies of Dr. Junkenstein. There are only four playable characters in this mode, McCree, Ana, Soldier 76, and Hanzo.

Each player chooses one of these characters and must work together to fight off waves of robot enemies, as well as some familiar faces. So prepare yourselves for combat as we all desperately try to unlock that Mercy costume.
