Scream Fortress is an anual "event" set in Valve's free to play first person shooter, Team Fortress 2.  This year though, things are a little different, thanks in part to an additional co-op mode that was added over the summer.   The free update includes a haunted map where random spells are cast on players, for both good and evil purposes. The two-week-long event, which starts now and ends on November 8th,  will also let players cast their own spells to buff their equipment like "shifting paint colors, ghost summoning, flaming footsteps and more."

It seems so long ago that we got that surprise free update for Team Fortress 2, one in which added the Mann vs Machine co-op mode for 6 players.  In reality, it has only been two months.  One complaint we had with the mode was that it was pretty friggin hard, combined with some match making difficulties, it didn't quite catch on with us as much as we thought it should.   A new update for the game directly addresses both issues and adds new content to boot.

Team Fortress 2 is an incredibly popular game from Valve that has had pretty consistent content updates for the better part of the last 3 years, and I don't just mean the hats.  Now the game is getting what some might consider the biggest update since release - and entire new "faction" of of characters have joined the game.  Except these aren't Reds or Blues, rather these are machines and it's time to team up with your friends against them in a survival mode.
