If you have a couple of hours to burn on something completely and utterly ridiculous, you might be interested to hear that Ultimate Epic Battle Simulator (UEBS) is currently free to grab. Simply head on over to Steam, click on that giant green button, and you'll be able to start playing right after a brief download.

As always, the only catch is that the whole promotion is time limited. So make sure grab yourself a copy before the whole thing ends on February 1st, after which you'll be able to play UEBS whenever you want.

When it comes to the quality of the game itself, it should come as little surprise to hear that UEBS is mostly a gimmick and something you'll only really play a few times before moving on. Because of this it's not something I'd recommend buying at full price, but considering that it's entirely free right now, it's probably worth checking out purely to see how insane things can get when you spawn 10,000 zombies on the same map.

Have fun, and I'll leave you with one of the trailers highlighting a battle between the forces of Christmas and Halloween:
