An Expansion Pack is a direct addition to the main game by adding new maps, creatures, equipment, and content without changing the core game-play mechanics.
Expansion Packs are also entirely compatible with the main game, and content can be transferred from an expansion to vanilla servers and vice versa.
An Expansion Map is a brand-new map for the user to explore and uncover its secrets.
A Total Conversion changes a majority of the game-play mechanics themselves and requires a user to learn a new way to play the game.
Content from a Total Conversion can not be transferred to a Vanilla server.
- Interestingly almost every expansion pack has 1 up'd itself adding in a new largest creature in the game with the Alpha Deathworm surpassing the Titanosaur, Rockwell surpassing the Alpha Deathworm, and the King Titan surpassing Rockwell.
- However, Corrupted Master Controller is not as large as King Titan following the release of Genesis: Part 1.
- Despite not appearing as big as King Titan, Rockwell Prime's insides have eroded into much of Genesis Ship in Genesis: Part 2, making it the largest in terms of map size influence within the entirety of expansion pack.
