They really do need more achivements.
Heres some off top of my mind

Zombies! Play zombies
Rabbit slayer, kill 50 rabbits in nuclear plant
They see me drillin', kill a person with the drill
DAMN! Its cold! Shiver for 1 hour
Me djsta, buy a dj mixer
Lights off... Buy a dimmer
Stripper, go on the stripper pole for 1 hour

Why would you care about more tazers and hunters? If this was before era sold daggers then i would have aggred, but theres already a ton of very fast melees out there so really it wont matter. If a person didnt have a hunter or tazer tey could buy brass knuckles witch are one of the fastest melees in game for 2k. So why complain about a fancy melee that adds a animation when you hit someone when in reality a ghukura is the same thing basicly with no animation?
