tips and tricks
Here is some advice for the game.
1) When the enemies land on the ground they move towards you. So if you havent fired a shot move quickly out the way.
2) When your rookie status changes to killer the enemies move faster. Sometimes fire shots inbetween moving back and forth.
3) Try to look for patterns in the enemy movements , it helps later on when they are comming faster.
