Ah I miss this game. Great customization options, cool music, great weapons and combat. I feel it didn't get the love it deserves.
I played it mostly with my brother. I nearly always played Ranger and loved that you could aim in first person. We were fighting some big flying demon bat boss which my brother countn't reach. Not thinking too much of it, I fired at the demon and just kept going for the wings. The delight when I damaged them enough for the boss to come crashing down to earth and my brother running in and tearing it up in melee. Sounds really daft now I suppose but having that "OH MY GOD IT WORKED!!" moment was really fun.
