Oh, I've taken to using this move that I saw someone else do, and I memorized it.

1. Relax all
2. Contract both pecs.
3. Raise both arms.
4. Contract both knees.
5. Press space.
6. Extend both knees.

From this, I can sometimes rip their head and arms off. I didn't make this up, I just mooched if off someone else. It's must better than mine though.
That doesnt help him out much... Just do what this "Frederator" man says, and you'll invent some decent moves for this mod. I can't really help much because I dont play it.
