The Vanquish demo is out now, waiting for you to download it on the Xbox Live Marketplace and PlayStation Store. To bring you up to date, the Vanquish demo allows players to play one level with your choice of two difficulties, casual or normal (Of course, I picked Normal). Taking on the role of Sam, a United States government agent with a futuristic ARS battle suit, players must use an array of weaponry, upgrades, and unique Boost and AR mode abilities to take down those evil red robots. My favorite ability so far is the super boost power slide, which can take out enemies with ease; it's also a killer move to perform at a rock concert.
Check out the first 15 minutes of gameplay from the official Vanqusih demo.
