I'm on phase 3 now and i almost don't do crash sites anymore because i need to spend OP to do them so i just collect the bounties, am i screwing myself over by doing this?
I use 2 shields, 2 assaults, 3 riflemen and maybe 1 heavy or another assault sometimes, i think snipers are too map dependant and haven't tried grenade launchers.
My basic strat is open a door, smoke everything and rush in with shields and assaults, they kill almost everything while riflemen support from the entrance
And how do you handle base upkeep? i make so little money and my base isnt that big, when i build a second one im gonna go on the red
