We need to add a criteria for achievement suggestions. Requiring them to be puns. Puns or cultural references. Otherwise I'm afraid I may need to kill myself...
Misogynistic Dinosaur: as Bond, win a round where 75%+ of your kills are female characters. (this may be better suited for when we have more female characters to choose from, unless you want to act like a manic on the server and stalk Mayday and the science lady; the conditions can be changed if deemed to easy or too hard).
The Moonraper: win 5 deathmatch rounds using only the Moonraker Laser, rack up more than 20 kills and die no more than 5 times. (the name may sound a bit offensive to those more sensitive, and the conditions can be changed if deemed to easy or too hard).
Revenge of the Nerds: as the scientist(s), win 5 rounds of YOLT using nothing but the DD44 and/or Grenades (4+ kills).
These are just suggestions, of course.
