Game needs mode with no enemys to hard to complete.

The game needs to have a mode where there are no enemys because I think that the game is to hard to complete because at 60 minutes the enemys get over powered and kill you in second and you cant get everyone back in 5 second so you have to fight 12 enemys with 2 guys so of course you die and cant complete the game.
