Igor's Mod - This is a sandbox mod / utility for DooM II, inspired by the game Garry's Mod. At the moment, it is possible to create most of the actors in the game, delete them, make various manipulations with the inventory, activate and deactivate many console commands, and much more. With the second update, a physical cannon and add-on support appeared in the modification. (One addon as an example comes in the archive with the 0.2a version of the mod)
