To find these weapons, go up to the search bar in your spawn menu, and type in "sfw," it will bring up a list of all of the weapons in the mod. There are a few weapons that don't appear under the regular weapons tab, but are completely modeled and functional with unique aspects.

These include the..
-Prisma Wrath (sfw_prisma_wrath) a higher damage version of the prisma, with a spin-up effect.
-SMG (sfw_smg1) an upgraded version of the HL2 SMG, with a much stronger alt-fire.
-Alchemy Wrath (sfw_alchemy_wrath) an upgraded Vectra, with a stronger alt-fire.
-Phasma Wrath (sfw_phasma_wrath) A better version of the phasma blade.
-SG550 (sfw_sg550) a sniper rifle with extremely high zoom.
Most surprisingly:
-ASA-6 EBR (sfw_asa6) a totally unique, modelled, and functioning SWEP, basically a DMR.

Near-finished weapons
-Z644 'fang' smg (sfw_fang) an upgraded P90 with a gorgeous model and muzzle flash, complete with an amazing sound.
-HS16-CC 'Helios' Pistol (sfw_helios) This weapons is odd for a number of reasons, the inspect menu shows that the weapon was intended to have special effects, AND because the name is capitalized, unlike the fang. The weapon's stats page is copied from the Trace revolver.

Placeholders/Tests
-RNR 'Meridian' Shotgun (sfw_meridian) A shotgun that shoots a slug that splits into multiple projectiles upon ricocheting against a surfece, like the Trace alt-fire, but with more pellets.
-sfw_ignis (sfw_ignis) A flamethrower with a P90 model and no special text, still functions.
-LN0 'Azure' Grenade (sfw_azure) A massively buffed HL2 grenade, featuring sticking, a bugbait model, and functioning visual effects, but no stats page or description.
-"Yet another sci-fi weapon" (sfw_basetest) As the name implies, it's a test weapon, featuring an SMG model and tracer.
-T3i 'Cryon' ice grenade (sfw_vprnade) unlike the real Cryon, this one doesn't freeze enemies.
-CCX3 frag grenade (sfw_frag) a massively buffed HL2 grenade, with a much shorter fuse.
-Z82k 'Thorn' Pistol (sfw_thorn) a deagle with a unique muzzle flash, no other details.
-vk21 combat rifle (sfw_vk21) a FAMAS with a unique muzzle flash and sound, featuring a slightly altered model
-MIRV Grenade (sfw_frag_mirv) a frag that splits into more frags

Darken, please don't remove these weapons or hide them. As someone who takes an interest in game design, it's nice to see this sort of design process, or the leftovers of it, kind of like cut content.
