How submission works inufc 2009 undisputed?

Answer 1

okay submissions are different depending on if your going against a CPU or Human,

For CPU: make sure they are fully drained (gassed) and if your going for a Knee Bar then kick the leg you are going to Knee Bar . other than that it is really hard to submit the CPU just try and get the Stamina Advantage and keep on trying to submit them

For Human: very simple, just wait till they are completely or almost drained (gassed) and Tap A rapidly to submit them (do same for CPU).

That's about it

The Rear Naked Choke is the most powerful

Answer 2
