That is correct, I simply said rifles since I wasn't sure if it was only repeaters that were meant to attack twice given how inferior two-handed blasters are to single-handed. I suppose repeaters were meant to be an upgrade to fill that niche. I wonder if it would be possible to restore?
The fact that blaster rifles don't attack twice was a bug in the original game, so I wonder why they didn't fix it in 2. It creates a serious inconsistency with melee weapons, making ranged weapons even less useful.
