For the next 48 hours (probably less now), Assassin’s Creed 2 Multiplayer is available as a free introductory download. After that it will be $3 so you’d better get over to the App Store and get it while you can. The game is a simplistic top down perspective multiplayer game where 4 assassin’s kill each other over Wi-Fi in 3 different AC2 environments.
The game has 6 power-ups to use as well as integrated leader boards and a friends system for matchmaking. Definitely cool for free. Let us know what you think!
