Angelic Aviary is an enemy replacement mod that pits Doomguy against the forces of heaven; beautiful angelic warriors bent upon freezing the earth solid and incorporating it into heaven. All enemies are custom made with new art, attacks, sounds and abilities.

-Highly balanced for vanilla gameplay.

-Lots and lots of Easter eggs, including hidden enemies only accessible with select map packs and weapon mods.

-Slimmed down Zandronum version for fighting angels with a friend.

Gameplay

Appearances can be deceiving. Behind the cuteness lies the spirits of warriors who have fought off both hellspawn and human. Compared to demons, angels tend to be more aggressive and dangerous in mobs, but less spongy and easier in one-on-one fights. As the majority of the angels are fliers, they flock in large numbers and can easily surround and overwhelm a slow player.
Learning to prioritizing targets is fundamental, even more so compared to vanilla doom. Certain angels if not put down quickly can resurrect their sisters, summon massive armies or fully charge up to unleash a massive flurry of bullets. Some angels will even require the player to think about when they're going to kill an enemy as killing certain enemies at the wrong time can led to severe consequences. Learning each angel's quirks, exploitable weaknesses, and how she both functions alone and in a flock is key to survival.

Note: Infinite height MUST be disabled!! They are alot of flying enemies!
I also recommend turning on freelook and disabling autoaim.
