First of all stay in groups of two. Try to resist wanting to steal the other groups points and then leaving your team mate by himself to get killed which happened to me today.
Secondly SAVE your points. There is no point buying the sniper rifle at wave 10 as the enemies are all low level greens and monkeys. That means you just wasted 650 points that could have bought you the rifle at 45 - 50. Try to refrain buying anything apart from 1-2 medkits till wave 20.
Price list for needed weapons and equipment
Medkits: 150
Chaff grenades: 450
Sniper rifle: 650
Shield: 1000
Here is a purchase guide for each section of Invasion: (FOLLOW IT TO THE LETTER)
Waves 1-10: Buy nothing!
Waves 10-20: Buy 1-2 medkits depending on skill
Points needed: 300
Waves 20-30: Buy Sniper rifle, 2 medkits
Points needed: 950
Waves 30 - 40: Buy sniper rifle, 3 medkits, 1 chaff grenade
Points needed: 1550
Waves 40 - 50: Buy Sniper rifle, 3 medkits, 3 chaff grenades and a shield if you volunteered.
Points needed: 3450
so yeah your sub weapons go away after those 5 rounds, so ill try to refrain from getting the snipers every round. maybe on our later rounds pull a guardian cuz the killers will have more points than the shield guys. groups of 2. etc
