This is combo for getting two achievements at one time.
In multiplayer (if you want Relentless) begin with settings, choose Robot and set minimum possible arena and damage modifier 1.5-2.
In game you use chainsaw, after use CONCUSSIVE BLAST. DI is zero in start but you piece by piece increase DI to maximum toward to you. Look this combo:

Another tricky method. Set MAX DI scaling to 1 (only this) and choose Robot. Make TRY CATCH as Robot and jump as the other character. Spam TRY CATCH untill you win.
You can ask me: "But this achievement requires basic match settings, yeah?" Yeah, damage, hitstun, cancel, and resources must be basic, but other settings can be anything.
It can be used for previous two achievements.

Just invite your friend and make Starting meter is 9.99. When match will be started, you and friend will be getting this achievement immediately. Don`t switch on Infinite Resources, else you aren`t going to get achievement.

Just open style editor (Customize), make a style and save it.


If you were not getting achievement, restart game and make style again.

Singleplayer. You select Wizard and any other character, 2 starting scales of Super Meter. Make a Spark Bomb, and jump on bomb as another character.

Singleplayer. Just make two hits as one character and after Burst as another player.

Ask your friend to help you. Choose Cowboy, friend can choose anybody. You are making Impale when friend use any move for getting caught by your Impale.

• Singleplayer
  
• Minimum width of arena
  
• Choose Robot
  
• Command: Grab -> EARTHQUAKE
  

Invite friend to lobby, make 3x damage modifier. Just go back from each other and wait. After getting SAD!, wait for SADNESS. After getting SADNESS, start to hit your enemy friend and kill his character. It will be fast cause SADNESS increase getting damage to 150%.

Spam Tome Slap with opponent`s DI directed toward you.

If you were not getting achievement, restart game and make sneaky style again.
