I got the shishkabob skill in prospector, also the repairman skill there too.
I think I got those two there as well. A few others too, but its been so long I can't remember any others for sure
I can't remember if you can earn the Weapon skills in Prospector. You'll just have to try it out for yourself. You can earn some skills in Prospector, but not all, and I can't remember which ones you can and which you can't.
I took out at least 50 enemies with the sniper rifle and didn't unlock the skill (though I got Shishkabob about 10 times over during that span). Doesn't look like you can unlock the weapon skills in prospector.
Nope. You threw up some air mines... but your teammates were defending them like it was an objective or something...
Edit: Actually just checked my skills... Hyper-aware and Low Profile are unlocked.
In Prospector (solo) I have unlocked Scavenger, Marksman, Fast Lock and Engineer. None of the weapon skills seem to be possible.
For Fast Lock (Anti-Air Medal), it was round 3 of the Severed Ties Prospector map. Your rig is attacked by about a dozen Hawks. Takes two rockets to kill one on Normal difficulty, so you'll need to keep a bunker alive to reload.
I just unlocked the spawn with a shotgun skill.
i unlocked the weapons ones in arena DM games. I would just spawn in on that weapon and keep killing until I got it! That spawn with shotgun is key for DM.
