swap weapons with Q and E or use the mouse wheel. you dont pickup a crate, that would be too easy, you have to push the crate back to the base. and to the others who are wondereing and have commented, there is no amount of day, thats why its called "ENDLESS zombie rampage 2"
wars is not always range, it will be more realistic if there where melee combat such as now, and if i was urbz i wouldnt remove close combat. but the bayonet idea for faster kills is a good idea, it should cost like 1 tp
cam net hides you from airplanes. if you noticed when you have over 6 on your team and then a airplane spots you then it will be a good idea with a cam net before getting more than 6 in your squad
damn they upgaded this to a nightmare difficulty. i have hard coming to wave 50 now and if i dont build a cam net i get a airplane bomb in the head at wave 10
