Ok fuck this defeat the streak undertaker mode. Some of the cheapest ai ever and I fucking finally wear his ass down outside the ring and am able to get back in the ring with him and hit a finisher and pin him thinking I finally won only for the lights to go out and his ass to pop up behind me in the ring with a finisher stored. Needless to say I lost.
It's really easy to beat him once you figure out how to circumvent his bullshit (the lights going out when he's in yellow damage, finisher from the ground when he's in orange, no sell when he's red). Immediately go outside the ring on the left side and get the sledgehammer from under the ring. It's always there. Just do running strikes on him outside the ring. If he reverses it, you can just grapple him and take the sledgehammer back. When he's down, hit him in the head with the sledgehammer one time. Just alternate between one running strike and one grounded strike. When you get your signature and finishers, do them on him once outside of the ring. NEVER pick him up off the ground, or he will hit you with the chokeslam or Hell's Gate. Let him just get up on his own for signatures or use the taunt getup for finishers. Once you've hit him with a second signature outside the ring, pick the sledgehammer back up and run into the ring. When he gets into the ring, immediately hit him with a running strike to put him down. Wakeup taunt. Finisher. Win.
I've done it with Diesel, Kane, Batista, and Michaels without getting hit once. This way works great because you're using offense that can't be reversed into damage, doesn't give him time to initiate offense, keeps him grounded, and is so damaging it bypasses all his gimmicks.
