How do I install DELTA:Evolution?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This Alien Evolution addon adds a large handful of DELTARUNE-related powers and items. Most notably, four (two secret) transformations and one item:

Ralsei Transformation

Fluffy boy, low HP but can heal others or himself.
for the bit, has a cigar he can smoke to inflict status effects onto opponents.
Can ACT to increase his Tension Points, which lets him use his healing magic.

The Roaring Knight Transformation

Extremely powerful
Variety of attacks such as shooting out star projectiles which explode into arrows
Can summon a strong blade, however cannot detransform until it has been retrieved.

Devil's Knife Weapon

Scythe, cut and swing, swing!
Uses voicelines from the Jevil bossfight for the moves to feel more dynamic and active
Quite powerful, making the user evasive also.
Obtained using 3 key pieces from across the 3 base minecraft dimensions.

2 "Perfect" aliens hidden in the code. Only one has full powers and function, the other has mostly customizability.

That is all for v0.1, the first version. I have worked on this addon for about 5 months now with an associate, @dogedude1234 on discord (Credits to most item models, most item powers, and some help with concepts/designs).
