Kill 10 Evil Horny rabbits

You need to kill 5 white rabbits to spawn 1 black rabbit, so you'll need to kill 50 white rabbits to get 10 black ones. It doesn’t matter if they’re mating or not.
Just find two rabbits mating, save your game, kill them, then quick load (F4) and repeat the process until you get it

I’m playing on Normal mode to make these achievements easier to get
----------------------------------

• Bloodbath (Tier 1,2,3,4)
  
• Slaughterhouse (Tier 1,2,3,4)
  
• Hell On Earth (Tier 1,2,3,4)

The best way to do this is in Chapter 16 when you reach the big bridge.
You’ll need upgraded rockets and the Shockwave ability.
When you get to the enemies, use Shockwave to bunch them together. Once you’re ready, jump and shoot a rocket—jumping makes it easier to aim.

When you get the Shockwave power, use it by pressing (W, W, then hold RMB). It’s recommended to fully upgrade it. When enemies are on the ground, use Shockwave to kill them and make sure you earn the Sleepyhead achievement when you do.

I’m not sure exactly how this one works. If you can let me know, I’ll add the details.
