Since there is no confirmation on what the achievements will be for the game, aside from the time being, let's create our own!
Here's some of mine:
"KEEP IT CLEAN - 10 GS: destroy all environmental objects within the city."
"Terminator - 50 GS: Never use a health pack"
"Ray Charles? - 50 GS: Never use the low-light mode, VISR"
-
How'd You Do That?-30 GS: Kill a Brute Cheiftain with a Plasma Pistol, with no help, or any other shots or melees added Ninja-10 GS: Assassinate a Brute Cheiftain before he activates his Invincibility ODSTs Can Be Spartans Too-50 GS: Survive 15 (or 10) rounds in a row in Firefight on Legendary mode with just one player and without dying Extermination Was So Last Season-40 GS: Get four Killonaires (one in each round, and the rounds are in a row) of Firefight These seem like real achievments that would be in the game.
