Doom mod weapon showcase: OSJC's Major Crisis
This is a pretty cool oldschool-style weapon mod that also comes with an add-on containing a few new weapons and a monster pack on top. It does things a bit differently than your usual Doom mods, but I can safely recommend giving this one a spin as it's a lot of fun. :)
I will say I didn't show *everything* the mod has to offer. There are pipebombs and at least one unusable weapon, plus some more inventory-activated items. The main reason is I have no idea where those actually spawn.
