Two SquareSoft (pre-SqEnix) RPGs for the PS1. Makes a hash out of biology for an excuse to shoot grossly mutated critters throughout NYC, an office building, and a conspiratorial desert area.
Aya Brea the protagonist blasts everything to hell with a wide assortment of firearms. PE1 was fairly freeform: guns, named 9at least) for RL firearms, had various base stats, bonuses (+1 to damage, etc), and special qualities (three-shot burst, nitrogen rounds, etc). Aya can rip them off of one gun to put them on others.
This leads to truly inspired weaponry, such as the H&K A101: a Heckler & Koch G3 battle rifle remag’d, rechambered, & rebored for 12g shot shells, with roughly a 35-shot mag capacity or so, three-shot burst capability, and the shells themselves loading tranqulizer-tipped flechettes.
(Fortunately Ammo was generic. Add in the Cyanide effect and that shit just isn’t available in stores. 
)
PE2 tamed that somewhat by adding a broader variety of guns, but removing the customization. So you can get an M4A1, a .44 Magnum, a Calico M950, an M249 (both full-auto, and Aya handles it just fine, kthx), an MM1 rotary 40mm launcher, and a massive shoulder-carried railgun that takes 5 seconds to actually discharge.
The magical mitochondrial powers are nice too.
You should check it out if you’ve got a playstation sitting around. IMO each is worth around $10-25.
PE3, incidentally, is pretty much a letdown. Stick with the first two.
