The Final hoarde is undefeatable but there is more than enough ammo in the game for you to wipe out the enemies in the Sci-Fi base. Also another quick note, you must have your graphics lowered to be getting those uglier textures, try turning up your graphics, also the amount of enemies is realistic to the storyline, the sci-fi base held thousands and was invaded by the virus. Try replaying the game at a higher setting and looking for ammo and then you may discover some more enjoyment. But if it wasnt your cup of tea, then id advise you try TV189 - Sandstorm as it has more firefight and not as much hoardes of enemies. Thanks for the feedback though.
