All the achievements now have descriptions next to them.

Nice! There are some really intresting achievements there. With the regular "Kill 10 spies while they are cloaked"

Agent, everyone loves killing spies when they're cloaked. Its nothing personal

I'll light em, you fire em fatty...

Hmmm we were right about the gloves the slowing minigun and one of the achievments its eat 100 sanviches who reckons we are right about the shotty being replaced by a sandvich ?

Krazy Ivan: Kill 100 enemies while both you and your victim are underwater.

WTH? Almost impossible to get during normal gameplay...

Maybe new maps are underwater and you get snorkels or something lol

Some of em are just stupid, but most of em i get legit over time

A lot of these achievments are the same in the Pyro pack, killing people underwater and kill 10 cloaked spies. And the one when you kill 20 with a medic is also a medic achivement

Heavy Industry: Fire $200,000 worth of minigun rounds in a single life.

Easy. At the start of the round, stand next to the locker thing that heals you (I can't remember what it's called for some fucked up reason) and gives you ammo, and continuously fire your minigun until you get the achievement.

You don't even need to stand next to the locker, it's only 6 seconds of firing
