Alright. In Rainbow Six:Vegas there seems to be a glitch in one of the achievements. The other day i was doing a splitscreen game with a friend of mine in Normal Terrorist Hunt. I completed every map in one sitting which took about 4 hours with my friend. We did not get the achievement. Instead we got the Tour of Duty achievement instead of Veteran Hunter. Here is what the two achievements state.
Veteran Hunter: Complete all maps in splitscreen Terrorist Hunt on Normal difficulty.
Tour of Duty: Cooperatively complete all Terrorist Hunt missions.
They seem the same but I played this on splitscreen so i deserve the Veteran Hunter even though Tour of Duty is worth more. But now my question is sense that i have Tour of Duty, How do i get Veteran Hunter now sense i practically did it.
