The Voidspears are because I've tinkered with their AI and wanted to see if someone would notice : > Not finished with them yet.
Ferrocannon is more efficient, higher DPS, and has near-hitscan projectile speed, but costs more OP. And it's a large mount.
This weapon (Bolide Heavy Artillery) has 100 more range, and is a 15 OP cost medium. Unlike the Ferrocannon/gun, it can miss shots a lot of the time thanks to its 450 proj speed. Burst jetting backwards while firing will make your shots about as fast as a proximity charge, burst jetting forward will make them on par with a HVD or mauler. Plus the fact you can sling them sideways as well.
Current stats are 600 kinetic/shot and 900 flux/shot, 150 dps / 225 flux/s, 1000 range, 1 degree min spread and 4 max spread with 2 increased spread/shot, 90 non-regenerating ammo, 4 sec reload. Deals 100-200 extra frag on impact whether it hits shield or not.
The potential performance from this weapon is great, but hitting every shot is hard unless you are shooting at a big target.
