Haven't seen one yet, estimate about 320 hrs on ps4. Mostly in operations some skirmish. Played story to op 13 but save corrupted. I loot the skirmish even if I don't get to keep the weapons as they might be a temp upgrade to what I have.
Bolt pistol is single fire impact. What's the difference between heavy bolter and heavy stub gun (also impact)? Less damage more range?
Bolt pistol is deadeye only weapon. Other pistols are usable by all so more prevalent. Most AI deadeye seem to use lasgun or autogun because of longer range probably. There are level 5 and 6 bolt pistols and can be a fun alternative for up close combat.
Got a Heavy Bolter (rank 4) from a random crate. Was really looking forward to getting more from the Infamy-purchased reward crates at the start of my next Operation, but all my accumulated Infamy has been stolen by the November patch. I can't buy any crates to roll for new weapons
An enemy ganger was using a Bolter, so I nabbed it. Sadly it was Rank IV. I haven't had any luck finding Bolters in crates or the shop, but Heavy Bolters have been appearing.
Also stole a Rank V Meltagun, so I can finally begin converting my gang into Sisters of Battle XD
Found a Rank IV Power Mace (the Lay Mechanic attachment weapon) but I don't use Lay Mechs anyways
