With Halloween just around the corner, Steam has put a co-op favourite on sale for a limited time. Until Monday at about 1pm EST, you can pick up Left 4 Dead 2 for just $4.99 US -- down from $19.99 US and a solid pick up if you're a fan of first person zombie shoot 'em ups. Even if you're not that interested, you can play for absolutely free until Monday afternoon which makes this a good time to try before you buy!
We've seen Left for Dead and Left 4 Dead 2 on sale during the larger Steam sales but if you were hesitant for whatever reason, it's back on sale. As mentioned above, if you just want to try it out, you can play the full game for free until the promotion expires.
The game is pretty scary and features lots of gore, blood and violence so you'll want to keep this away from the young ones. It's fun to play solo but definitely more enjoyable with friends. It requires Steam to download and install.
