Game developers have begun kicking off their Halloween events early to allow for ample playtime, and that even goes for Valve this year. Team Fortress 2 is on its tenth Scream Fortress event, a fact I didn't particularly care to know but now can't seem to stop thinking about. This game just does not quit.
If you've long since moved on from TF2, the Halloween celebration probably won't bring you back into the fray. Scream Fortress X has five community-made maps to run through, Contracts (read: challenges) to keep your attention, and a batch of cosmetic items to earn over the next several weeks.
During the event, you can log in to claim a Soul Gargoyle which enables Halloween item transmutations, lets you work through Merasmissions, and uh, eats souls. Valve has added five new Contracts and also reset the objectives from prior years so players have the opportunity to finish them again.
Why bother? Because you need to look your spookiest! Clearing out a Contract will net you a free Halloween item and a chance of earning a Violet Vermin Case or a Scream Fortress X War Paint Case.
