Huh
I went with, at the start:
1. batarang (LTx2), then immediatly batclaw (RTx2)
2. counter (Y), then immediatly evade (Ax2) and stun (B)
...now hit them until combo x5
3. grab (X+A)
...hit them until x10
4. takedown (Y+B), then make some space with hiting them and finish it off with a ground move (RT+Y)
Sweaty
