Plas-39 accelarator rifle, gp-31 ultamatum as secondary and stalwart as support.

Accelarator to take out the annoying heavy armoured guys, ultamatum to blow up ships in 1 hit and stalwart to take out the hordes.

Only issue I have is the strafing runs and my friend sitting still to shoot at hordes instead of completing the objectives. They keep coming if you sit still. All 3 enemies keep coming if you sit still. Move!
