Shotlock from Kingdom Hearts Birth By Sleep, got a tutorial for it an all, but I never found use for it (until the end where a guide reminded me that it still existed) Its useful, I still never used it much once I remembered it.
Unfortunately it's also the easiest way to beat the Mirage Arena-specific boss.
I liked the idea behind it and all, but staying still long enough to get a full lock on enemies was almost always a bad idea.
OT: Crossbows. In most games, really, but what comes to mind particularly is that and the spear-thrower in the first two
Bioshock games. They do a lot of damage, but you get them so late in the game, by that point you're already overloaded with other things to kill enemies.
I would say vibroblades in the
Knights of the Old Republic games, but there's a lot of qualifying to that. But for the main character, at least, I'd never use anything except the lightsaber after you obtain it.
