[Update]: Dying Light's crossover event has added Left 4 Dead's Bill and the majestic Gnome Chompski.

In collaboration with Valve, a bunch of Left 4 Dead 2 community members have gathered together to release an absolutely massive new update - The Last Stand. I'm not overstating its size either, because The Last Stand has added a little bit of something to pretty much every aspect of Left 4 Dead 2!

You can expect to see a brand new campaign, 26 new survival maps to test yourself against, 4 new scavenge maps to remind you the game mode even exists, 2 new melee weapons, and in a rather surprising move, the official implementation of Counter-Strike: Source weapons! The Left 4 Dead 1 infected have also received their original skins, a bunch of previously unused voice lines have been added in, numerous animations have been spruced up, and naturally, there's a whole bunch of balance changes and bug fixes to round things out.

If you're wondering what all of this looks like in actual gameplay, you'll find your answers in the recently posted trailer down below. Have a peek:

While the new campaign is brutally difficulty, it is worth mentioning that it's also fairly short and contains only two maps. A bit disappointing to be sure, but the update is definitely still impressive and well worth checking out. Also, Left 4 Dead 2 has had Steam Workshop support for a very long time now, so if you're in the mood, there's plenty of user-made campaigns to try out!

Have fun with The Last Stand, and if you're curious about all of the details, you can find the full patch notes over at Steam. Needless to say, it's a pretty long list!
