NOTE: All Cvars are dynamic, meaning they all take effect after changed or as soon as possible.

From Main Mod:

• IPOG_EnemyPortalEnabled [0|1]: Enables / Disables Enemy Portals, which spawn more enemies periodically.
• IPOG_RandomItemStart [0|1]: After joining the match, players begin with a single item chosen at random, which can be: Medical Tube, Shield Recharge, Grenade, Proximity Mine, Time Bomb, Decoy, InstaWall, or Eye of Enlightenment.
• IPOG_Greed [0|1]: When players pick up the Bonus Item, all enemies currently on the map will become fast for a short time.
• IPOG_JewelDrops [0|1]: Jewels give points and are spawned on the map and after killing enemies.
• IPOG_AmmoDrops [0|1]: Small ammo amounts are spawned on the map and after killing enemies.
• IPOG_WelfareDrops [0|1]: Small health or shield amounts are spawned on the map and after killing enemies.
• IPOG_NexusClearance [0|1]: When the Exit Nexus spawns, it prevents the spawning of Bonus Items and enemies from Enemy Portals.
• IPOG_ClearStart [0|1]: The player starts with pistol and melee after map changes.
• IPOG_DangerBonusItem [0|1]: After picking up the Bonus Item, the next enemy portal's wave spawns only better foes (non-bosses still).
• IPOG_ExitNexusEnabled [0|1]: Enables / Disables the Exit Nexus mechanic.
• IPOG_AutoUseWelfare [0|1]: Enables automatic usage of Health and Shield items when low on them.

From Enemies Pack:

• IPOG_Spawn [value]: Spawns a set of foes according to [value]:
  0. Random Variants: It spawns foes from all sets.
  1. Desarian Orbital Penal Colony variants: A riot is in progress, so Prisoners may hurt and alert enemies to attack them!
  2. City Temple of Ristanak variants: No event mechanic is happening, but that doesn't mean it'll be easy!
  3. Mt. Kaal's Jump Base variants: Probes may be patrolling the map, meaning they may alert nearby enemies if they notice you!

• IPOG_WeaponDrops [0|1]: Weapons are dropped from low tier enemies, simulating Doom's original pattern. The weapons are:
  • Plasma Spreadgun: Trooper, Sorceress, KMan
  • Heavy Chaingun: Trooper2, Prophetess, KMan2
  • Flame Thrower: Trooper3, Berserker, KMan3

From Retribution:

• IPOG_Retribution [0|1]: Activates a new game mode: Retribution. Red Enemy Portals are activated on DM starts, and the only way out is via Exit Nexus. It's only compatible with maps with DM starts. Server hosts should also enable these Cvars to work as intended:
• sv_killallmonsters 1
• sv_nomonsters 1
