Purchase the Kitchen Sink game style
You need to buy this game style in the item shop. It won't show up until you complete the game, beat the challenge times and purchase every other item from the shop.
There are 8 Weapon Challenges and 10 Death Match Challenges. The Weapon Challenges aren't very hard apart from the Ikarus, Supersheep and Jetpack Challenge if you're not familiar with those "weapons". Just keep on practicing and you'll eventually beat Team17's best times.
The Death Match Challenges are much harder. Personally I found #9 the hardest. Here are some tips for the harder ones:
-------------------------------------------------------------
Tips for Deathmatch #7:
- In the cave at the back of the map (shown in the intro) is a crate that contains a Concrete Donkey - one of the most powerful weapons in WUM.
- Make sure to kill the 2 worms on the large rocks in your first few turns with the baseball bat. (Use Jetpacks to reach them)
- Place a dynamite next to the Worm sitting on the left wall so that he falls into the water.
- Kill the remaining Worms with Bazookas and Shotgun.
- Collect crates (they often contain powerful weapons such as Holy Handgrenades, Sheeps, etc.)
Tips for Deathmatch #9:
- First turn: Kill the Worm next to the campfire by firepunching him into the mine + barrel. This will also cause another enemy Worm to get poisoned.
- Second turn: Jetpack to the roof (on the right) and baseballbat the Worm on top into the water (this is a bit tricky you need the right position)
- Next few turns: Poison enemy Worms with poison arrows. Shoot a bazooka at the enemy Worm sitting on top of the left building.
- Once their health dropps make use of the Mad Cows and try to kill 3 Worms with them.
- Kill the remaining Worms with Shotgun.
Tips for Deathmatch #10:
Try to throw as many enemy Worms as possible into the water / into mines and barrels. Use Baseballbats, Firepunches or Airstrikes to do so.

Once you beat the game and all challenge times you'll be able to purchase these characters for 200 coins each at the shop: Alien, Cyborg, Dino, Professor and Wormstein. Do so and the Kitchen Sink style can be purchased for 0 coins at the shop and the achievement will unlock.
Note: If the Kitchen Sink style doesn't show up simply purchase all the other remaining items from the shop. Loyalty Items are not required.
