The Tessarct Ark kit comes with Tesla cannons as default, but the index also allows gauss cannons and particle beamers.
I put magnets on the tesla cannons, and now I'm looking for ways to supply gauss cannons and possibly particle beamers (not a very viable option in 8th, except saving points)
Gauss cannons from the destroyer kits would be one possibility, but I don't really have any destroyers to spare. The immortal/deathmark kit would be another good option, the gauss blasters could be built to resemble something when I build deathmarks.
Just thought I'd check if anyone had any ideas or had done this already?
