Overdose is a Doom 3 overhaul mod (for D3HDPv2) that aims to make Doom 3 more intense, bloody, brutal, violent & a more tactical-survival-horror-shooter. Enemies are faster, smarter, more aggressive & deal double to triple damage. The player's arsenal also deals double to triple damage. Player also moves faster. Still, Survival is not guaranteed. A quick trigger finger & planning your every move beforehand are essential if you want to survive.
Use this patch if you find Overdose to be too unforgiving. This patch adds many balance tweaks, while still staying true to the mod's vision of a brutal challenge.
