Too much weapons? That's an oxymoron...
Mm...reminds me of 1.13 MOD for Jagged Alliance 2 ... soooooooooooo many weapons... Tons of Gunz.... 200 at least.. yeah, that WAS a bit too much (not much difference between guns). The trick is to have guns with personality. So far I notices ammo is not a problem in the game. I rarely even reload once during a mission.
So a devastating, expensive, ammo-hungry weapon might fit the bill.
But I digress. I got a md2 importer but it doesn't work..I'll keep looking..
