X Com: Terror From the Deep?

I've been playing this game for a few weeks now but I get stuck at the same point pretty much every game I start. By month 3 or 4, Lobster Man and Bio Drones start turning up and kick the **** out of me. Gauss weapons seem to bounce right of them and I haven't got anything stronger to take them on with bar the Gas Cannon - which is a trade off in itself.





Can anyone give me any hints on how to defeat them? Is there a certain Tech that I should be researching to combat them?





Thanks, any advice is good.|||ok use this link for FAQ and strategy guide:
