Hey guys a mate and I are looking help with these achievements:
The Host with the Most
Places to See, People to Destroy
Kill Locust (Like a Boss)
Zeta Team, Go!
Defending the Past (Only need waves 45-50 any map, we can do the rest)
Unstoppable Force (Only need wave 50 on aftermath I think, can't get it with just the two of us)
We each have a spare controller each so for the hosting ones we only need one player, but we can't quite beat waves coming up to 50 so we only need help with a few of those waves.
My GT is PrivateAssassin, and my mate and I are both UK time. Any help is appreciated, cheers!
