Poltergeist

Click on the workshop and it will show you a list of 'recipes' available on that worktable. Different (basic, advanced, expert) worktables let you create interesting stuff. For example you can upgrade your medical station or create a teleporter (which will enable you to jump to all zones - requires all badges for a zone). There are also lots of ways to improve defence of your base.

Grav/Energy seems quite effective to me - hold 'em and blast away! White conned mobs normally drop before the hold is over (at least as soon as you have 3 Energy attack powers).

Well, you could give the collected salvage to your SG mates who own CoV. I'm sure they can use it.

Astonishing work! Sounds like a lot of it is really made for this game - I surely would like to see those ideas go live!!!

I'm with you on that one - although it's Propel for me!

Grav/anything - just because of 'Propel'. I love it (execution could be quicker though)!
