Description
Victory begins underground!

Follow-up to Rig 17/18/19/20 collections, which span a full episode each. The levels are created around interesting locations to explore (often with multiple paths to success), with specific visual and/or gameplay themes. Difficulty is medium-ish, with some levels being a bit easier and some harder.

Some tricky jumps, light puzzle elements, and plenty of runnin' and gunnin'. I don't like traps that require a level restart so if you think you got yourself stuck, don't worry. I tried to make sure there's always a way out.

There's no set order in which you are meant to play the levels, they appear in the order that I made them and they all stand alone. There are some returning themes though, like Wild West style maps. New maps will be added to the collection as I release them.

Feedback is welcome! You can leave a comment on this collection through the Steam Workshop, or on its own Steam forum thread. You can also join the official Discord of Crystal Caves HD's developer, Emberheart Games, at https://discord.gg/y3fSPtx

Rig 21 - GooLab 2021
Created by rotterdxm

Rig 21 - Cryo Chamber

Rig 21 - Manufacturing

Rig 21 - New School
Created by rotterdxm
Tileset: ONLY tiles not in the original DOS game (Roobar's challenge) Difficulty: easy Next to the snowy outcroppings lies the picturesque New School of Mapping. It looks very, very different from Mylo's childhood memories, almost 30 years ago......

Rig 21 - Regolith
Created by rotterdxm

Rig 21 - Magma Core
Created by rotterdxm
Tileset: deep core mine Difficulty: medium The choking fumes hide a horde of crawling horrors and hay-wire sec-bots. Word has it, however, that this biome's naturally-occuring Croppa Crystals are worth big space-bucks....

Rig 21 - Stone & Steel
Created by rotterdxm
Tileset: industrial Difficulty: medium The pipes in this decrepit refinery reverberate with the clank of security bots and the squishy hops of mutant slinkies. Probably best to turn on the lights as soon as you can... or is it?...
