SpaceTeam is an amazing game if you happen to be on the same room as your friend (separate devices though). Both players receive instructions on how to keep your spaceship going, and you have to shout each other the instructions in order to fiddle with the ship's panels and keep it working. Very, very fun Muffin Knight is another game that granted me hours of fun with a friend. It's like Super Crate Box with online multiplayer - coop and versus. We didn't like versus mode that much, but coop is a lot of fun. You both have to get the muffins while attacking and dodging the baddies. The catch is, each muffin you get, your weapon changes, and so change the way you will approach enemies. + coop, online, two players. As for local, same device multiplayer, my indie studio just finished making a fun competitive game. Name's Carmachia, it's a "top-down car arena", kind of a mix between Twisted Metal and Micro Machines. Two drivers get in, one get out. Each one controls a steering wheel on their side of the iPad, and the point is to blow each other with weapons like missiles, machineguns and invincibility shocks. I know you didn't ask for same-device multiplayer, but it's my baby and I bet you'd have fun with it ^^ Little teaser for the Blackberry version (game comes out around October 10th on the iPad): YouTube: video If I happen to remember more cool multiplayer games, I'll post them here
Heroes & castles is grat a multiplayer game IMHO so is blockfortress. Some others with multi device: - battle of wesnoth - battle academy (ipad only) - leviathan warships (ipad only) - worms 3 - heroes of order and chaos - cubemen 2 - magic 2014 (ipad only) - battle of bulge (ipad) - eclipse (ipad) - might and magic clash of heroes - frozen synapse (ipad) Those are my favorites hopes this helps PS: sorry i just saw now, that you need games for ipod 5... Stupid things rushing me...
If you're a fighting game fan definitely try kof-i 2012 https://itunes.apple.com/us/app/the-king-of-fighters-i-2012./id507938960
I'm also looking for two device multiplayer games but I can only use bluetooth to connect two devices. Any suggestions?
