What if we mix Ikaruga, that Bullet Hell with Doom?, IkaDoom Is that. IkaDoom is a modding exercise made in about 2 weeks, a very simple mod in which the gameplay of Ikaruga is brought into doom, bringing the 2 polarities black red - white blue to everything, as well as the absorption of the projectiles that you can unleash in a free and powerful attack, tested in GZDoom 4.7.0, and Zandronum 3.0.
