I'd prefer triple dance mat support if it's doable!
I'm getting hanging in Zombie Football Carnage too, but even without it the game is lame. It doesn't tell you how to play, either in a tutorial or in a menu, and that's ridiculous. And the enemies are so relentless that you've got about five seconds to work it out before you've been killed. So in my fourth game when I finally worked out how to play, I just ran around hammering the X button and, unsuprisingly, that's not a great deal of fun. You also still will die really quickly and to get enough money to upgrade your health and attacks, you'll need to play about ten games per-upgrade. And presumably they'll get more expensive. "Nice menu," is about the only good thing I can say for this.
Orbital Arena is alright, though. It's a multiplayer competitive twin stick (multiplayer ONLY) but has loads of modes. Normal "kill the most players" games, king of the hill, defend your base, and then some others. A Micro-Machines kind of mode where you kill a player to steal a star and whoever runs out of stars loses. Another mode could have been great but fails. Loads of numbers are floating around and you have to collect them, the first player to make EXACTLY 100 wins. It sounds great, but the numbers are so small I could barely even read them on a 26" display.
Hurdle Turtle Level Pack 1 is basically Hurdle Turtle again. I enjoyed Hurdle Turtle, but never really felt the need for more levels, because they're just the same with new graphics. Worth trying once at least just for the awesome music, though.
(I don't own a dance mat!)
