Guncaster is a WAD that works under multiple Doom-based games like Ultimate Doom/Doom II/Plutonia/Evilution and Hexen with Heretic. It's made by a Pillowblaster who is also in charge of Trailblazer. The mod itself changes a lot in the gameplay - you are no longer a Doomguy, but a dragon with super non natural abilities like dragon breath that puts enemies on fire, casting super effective thunderbolts, blizzards, daggers, angry crows and other spells which can be used by player. You are also able to purchase multiple upgrades like more maximum ammo, health, mana or faster mana regeneration, tiberium fused injections, additional TNT fuses, tank armor that gives your 400 armor points with 75% protection to you. You can also buy upgrades to your weapons which are really devastating in this mod - Matriarch Slug Cannon, Pulverizer Chaingun, 8-barreled shotguns and more. In Guncaster you aren't that fragile like in Brutal Doom or other mods, you are simply so great that you can fly and cast storms which fry your enemies very fast.
The other mod is probably very known to most of you - Maps Of Chaos gives a much more harder challenge to the vanilla Doom I and Doom II maps where you have to deal sometimes with more than 500 monsters on one map.
