RESIDENT EVIL RESISTANCE

This is one of the absolute hardest Mastermind achievements in the game. Keep in mind, you don't just need to hit them with Bull Rush punch. You also can knock em down by ramming them through Bull Rush. Which means you have two ways for Mr. X to down survivors for this achievements.

Of course, you could use equipment specify to Mr. X to increase his damage. System Devlog 1-3 and Control Glove does just that. However you also could consider using mostly or just one of the following to increase having Mr. X activated.

System Maintenance Manual 1 & 2 along with Control Glove. What I recommend is using a good mix of them. So having System Devlog III, System Maintenance Manual II and Control Glove. Which you should have 21 out of 25 points for equipment in place.

It is up to you if you want to fill the final slot for equipment or not. My recommendation is using System Devlog II for the final slot. Thus, Mr. X will deal a lot more damage with a lot more time to do the achievement.

I should point out both Devlog Manual 1 & 2 will also increase getting Mr. X more often. Which you may need to do this. It isn't hard to learn how to be Mr. X. The problem is your opponents which you can't fully know what you're up against.

If you want another tip, regular punches as Mr. X while using Windup skill. It will take longer than using his Brutality skill that quickly can knock down survivors. So whatever you have in your deck to get them weak enough.

All that will matter is if Bull Rush can keep moving without any close doors in your way. Any stun attacks will instantly stop this attack from happening as well. For Bull Rush, you'll need to run towards any survivor in hopes of knocking them down.

Now if you prefer using Brutality for something like this. Beat them up enough for their health to turn red. If no health items gets used let them run then use Bull Rush to quickly down them. Either knock two survivors down or just one of them twice.
