World of Kirbycraft: Chronicles of Uther
The movies, being years old, have strange terms that were retconned years after their creation. Here's the list of terms for the movies.

Orcs
Uther mentions being an orc a few times in the movies but in the fourth movie Arthas joins him but is still referred as "undead". Uther wouldn't switch factions so this is an incorrect term; The correct faction is the Undead.

World of Kirbycraft (ZDoom)
World of Kirbycraft (ZDoom) has many terms that may be unfamiliar to those either unfamiliar with the Doom engine and made-up terms. Here's all of the terms.

Area
Areas are just another way of describing "levels" to make the world Mary goes through feel like one big world and that she's visiting "areas" of it rather than set levels.

Tier
Tiers represent how powerful each monster is. A "tier 1" monster can be killed very easily, "tier 2" requires more skill to kill quickly, and "tier 3" are near impossible to kill without risking losing your combo and are the most powerful standard enemies.

"Tier 4" is for bosses only.
