How the fuck am I supposed to beat Frost? I try to run, but the fucker just knocks me on my ass.
he's a bitch, took me a while.
The first two rounds literally run away the entire time. Don't even bother throwing a punch. Just run, run and run away, and when he does get close, block. If you get trapped against the ropes, you can TRY to push him off. But try not to get trapped. The key here is to try and survive the first two rounds without going down (because there is a save point after round 2).
The next three rounds you have to land 75 body punches combined. This is the part that took me a while but what I ended up doing was in the first round (which would be round 3), just land as many body shots as you can and you can probably suffer a knock down or two (provided you make the first two rounds without going down) and rack up about 60 or so punches. Just do lots of combo punches to the body and remember to block.
In round 4, just run most of the round and survive.
In round 5, just run most of the round and single shot to the body every now and then until you get 75. After you survive round 5, the rest is easy.
