How to unlock the MultiSlay Champ achievement in Carmageddon: Max Damage - Definitive Guide
Have the player getting the kills pick the Cadillac, and the other player something fragile such as the rocket car or buggy. Player 2 parks with their nose facing a wall, then player 1 drives into them from a medium distance. This results in a kill almost every time, and player 2 will respawn right next to you making it even easier. The below clip shows just how quickly it will go by using this method
Other guides online suggest you can set up your own private games with options to set kill limits and time limits, but I have not found how to do this, but if you can get into a Car Crusher with a friend and trade kills back and forth (5 per match each plus 1 for whoever is going for the win towards the MP MegaPeeps), that'll get it done in a couple hours.
To complete this challenge, you have to wreck 5 online Opponents.
Each MP Trophy has 5 levels to finish so just exchange wins and kills with a boosting partner until you get it but each level takes more to complete than than the previous one did e.g. Level 1 is about 5 kills, Level 2 is 15 kills etc.
You must Wreck your boosting partner 75 times. Wrecking will take both players around 1 hour so set up a match unlimited time and unlimited crashes and keep wrecking your partner until the trophy pops. Smashing opponents into the wall helps as well and powerups usually spawn in the same spot so if you find a mortar, you can make this go a little faster by using that.

We put the card “Access to the stadium”, the race time and the number of points until victory are infinite, we go onto the field and take out the opponent.
On average it will take from 40 to 60 minutes.
