Mosch and I play it occasionally. It's quite good, and pretty easy to learn.
Basically, they work with action points. Every mini gets a certain amount every round, and has a maximum capacity. There are actions any mini can use (move, run, attack, dodge) but every mini also has a number of special attacks. Every mini has a card where all stats are noted, and there are cards for "equipment".
You can download the
rules for free on their website.
Also, Ulisses shows all the
cards on their forum. Just German, though, but I bet you can find the English ones too, somewhere.
