The game is very infuriating on Veteran and the grenade spam is ridiculous. I haven't played on easier difficulties, but the a.i. is terrible. Enemies kill me right next to my own squadmate. I'm on the second last level- Heart of the Reich. I managed to beat the rest of the game, but this level is insane. Several grenades get thrown at me. Tell me that the game was tested on veteran please, and your personal opinion about the difficulty.
