This is a remaster of @Fetex_Moderator's "Half life 3D". I have fixed frame rate issues, GUIs, and names. Gun, HEV Suit GUI, and music (Valve - Nuclear Mission Jam) are all from Half-Life (1998) developed and published (formerly published by Sierra Entertainment, who now has no rights over the franchise) by Valve Corporation.
