I noticed this too, and after over a week of not updating I removed my steam account and re-added it and it found the new achievements, but it still hasn't automatically updated since then (Going on 3+ days).
I remember when this came out way back and the graphics were mind blowing. It had an interesting and varied campaign, awesome creature selection, sweet physics with creature exploding into the air, multiplayer, and more.
Guys, has anyone got thier Logitech Rumbpad 2 to work with this game? I just got the game and the controller is detected, but the buttons are mapped wrong, pressing down on the left stick is moving up, cant attack (slight problem), and other weirdness.
I have a number of Steam games that are out sync with Giant Bomb. For example Torchlight and Left 4 Dead 2 have achievements that have been changed/deleted yet giant bomb has the old achievement still active. This creates the situation where i have all of the steam achievements on their site, but according to giant bomb im missing that one.
Im curious if there is a plan for GB to re-sync because this is holding back a number of S status's that i have.
Games i have with problems:
Left 4 Dead 2 - removed obsolete achievement (SPIT HAPPENS)
