Frantic single and multiplayer, following the rule of 2 thumb. Great graphics nice sound, and fun to player.
Single player campaign is longer than most arcade games, currently I have only made it to level 8, and I believe 2 player co-op would be perfect for the difficulty.
The graphics are pretty and clear and crisp, the sound is fine, nothing that impresses me too much. Controls are responsive.
Single player is fun, but nothing to keep you interested for many hours. Co-op is something I need to try out, but to be honest not many players on my friends list has it, I thin kjust one other!!!
Online multiplayer that I have played consists of survival, how long can you all survive against many, many, many enimies. This was fun, and there is certain tactics to keep everything going, and lasting longer. This part of the game I found fun and appealing.
All in all a good release for XBLA, nice to have original content, and lets hope more of the quality like this game come out.
