Well I've played a game on AKKA liek this a few days ago.
Hummies moved to blood room, sd came and a few of us managed to get reactor down, getting killed along the way. While we attacked, hummies attacked OM and killed it.
No OM, no reactor, shit load of playes alive.
While couple of us had 9 evo, no OM, no Evolve so we just went hummie hunting.
They held off for about a minute or two, using up their ammo. After that we just walked in and ate.
We had one basi left, so while dretches node sat, he killed the nodes.
