first off, reset your brightness and contrast to default. that will no doubt help you. secondly the crates are there specifically to obscure you from killin enemies behind them. you need to move around and kill as fast as you can. its not really that hard if you got rank 30 beginner items just make sure you keep moving and listening for the enemies.
