Game Hunter Question
Game Hunter 10G
Kill an enemy of every type in a single player campaign.
I've beaten the game twice already.
1st playthrough was for simply campaign completion with no side missions (and also finished in under 12 hours for "Blitzkrieg").
2nd playthrough was for all the collectibles and side missions (and surprisingly "Single Quarter" through the main menu quitting trick).
After my 2nd playthrough and under the assumption that, after going through all the main story missions, side story missions and killing the end game boss as well as everyone in every mission, I would get the Game Hunter achievement.
But I didn't get the achievement.
Is there something I'm missing as to how it's suppose to be done?
Any help would be nice.
