HaloWeps is a weapon replacement mod which oughts to bring some of the Halo CE feel to Doom without undermining classic Doom gameplay way too much. I worked on this for the last year or so and now the mod is in releaseworthy state (unlike my previous attempts on some mods).
All weapons in the mod have a primary fire, melee attack, most of them have reload animation and you can throw grenades while wielding any of those weapons. HUD has been redesigned to resemble HUDs from more modern Halo titles. It tracks health, shields, grenades, ammo, frags and keys.
This mod can be used with any vanilla SP/DM wads and most probably with any mod that doesn't replace any items.
