3 player strategy?

[PunchAPack]

Me and 2 friends are planning to beat the Easter Egg in a couple days having finally finishing Shang's, and attempt a really good game afterwards.

So what are some good 3 player strategies? We are planning to have 3 lots of Gersches, 3 hackers and a couple of us with 2 Ray Guns, and obviously perma perks.

Any good areas worth holding? Obviously Tunnel 11 is open because of the EE, any other areas?

Or will Biodome be our best bet?

How is the Cosmonaut typically dealt with on high rounds?

And whats our best way for hacking Excavators?

Thanks in advance for any replies.

Never mind, we just ended on 35, 2 of us had 2 ray guns and we ended up running the

biodome, finishing with a chaotic round in the receiving area.
