Other Features and Detailed Explanation:
Machinegun, Chaingun, Rocketlauncher fire multiple projectiles spread out per shot. These specifications will force you to fight in close quarters.
Plasmagun had overlapping functions with Machinegun, so it was modified to more closely resemble a sniper rifle.
Added "AutoShoot" function to Plasmagun, which automatically fires Plasmagun's bullets when aiming at a live enemy while holding down the Fire button. This function can be turned off by editing "weapon_plasmagun.def".
"fireRate","num_projectiles","noReloadIsRequired","infinityAmmo" parameters added on weapons. Now you can design your own weapons by editing "weapon_*.def" files, not script files.
SoulCube's damage is reduced to 100. Hence, you must (and can) kill the cyberdemon with your own guns.
Detonating a hand grenade in your hand will cause your health to fully recover. It also spreads strong splash damage, so doing suicide attack with a hand grenade in low health is now not a bad choice.
Double barrel shotgun consumes four shotgun shells per shot. This means that Double barrel shotgun is four times more powerful than ordinary shotgun.
Holding your fists in the air will regenerate your health. This regeneration speed depends on game difficulty. You can disable it or change regeneration speed by editing "weapon_fists.def" file.
Attacking a living enemy with Chainsaw restores armor. You can disable it by editing "weapon_chainsaw.def" file.
"armorProtectionRate" parameter is added in "player.def". This parameter sets CVar "g_armorProtection" that defines percentage of damage armor receives. Default value is 0.5( original value is 0.4 or 0.2 ).
"Light up enemies" feature is added.As literally, you can light up enemies whose trying to kill you. This feature will infringes Doom 3's beautiful graphics so is off by default.
"Item drop" feature is added. If this feature is enabled, enemies may drop items when they die. I feel this feature is not fit for 'Old-school Shooter', so is off by default.
You can change damage scales of each difficulty by editing "player.def" file.
While Doom 3's random function always returns the same set of random numbers each time the game is run, the "Random Encounter" feature will produce a different result each time a new map is loaded.
Added "Muzzle Flash" feature to weapons. It is off by default. The feature is enabled by adding "set runners_muzzleflash 1" to "autoexec.cfg".
"Auto Skip Cinematics" feature is added. Off by default. With this feature active, cinematics in game will play very quickly until its end. Set "autoSkipCinematics" parameter in "player.def" to "1" to activate the feature.
Sentries will no longer hurt you.
Enemies receive more physical impact when they die.
