A mod which re-implements the ten missing levels into Rune Classic, this guide contains download and installation instructions. Rune can certainly be a bit of a grind when played at full length (which I suspect is why these were dropped from the Steam release) but it seemed like it would be nice to have the option for them to be included in the campaign once more.

Installation:

I'd recommend making a backup of the maps folder before replacing any files in case you want to revert later without re-downloading from Steam. Also take note that loading a save game from a map which has since been replaced may cause issues in some cases.

To install, first remove the suffix '_CUT' from any levels within the ..\Steam\steamapps\common\Rune Classic\Maps\ directory. There should be ten of them as listed below. (Example, 'DeepUnder4_CUT' should be changed to 'DeepUnder4', and so forth)

DeepUnder1OdinB_CUT -Becomes-> DeepUnder1OdinB
DeepUnder4_CUT ---------------------> DeepUnder4
DwarfMap5A_CUT ---------------------> DwarfMap5A
DwarfMap3A_CUT ---------------------> DwarfMap3A
DwarfMap3B_CUT ---------------------> DwarfMap3B
Goblin1_CUT ----------------------------> Goblin1
Hel3b_CUT ------------------------------> Hel3b
Hell2End_CUT --------------------------> Hell2End
Mountain1_CUT ------------------------> Mountain1
ThorMap4B_CUT ----------------------> ThorMap4B

Now, copy the 11 map files from the archive into the folder, replacing the originals in the process. You're now ready to play!


What This Mod Changes:

Here's a list of what was modified in each level. 'Changed transition' refers to changing the next map to be loaded, while 'restored geometry' means I brought over content from Runes original levels so the transitions line up as they do in 1.07 and below. As a long time fan, I made absolutely certain to be faithful both to the original game, and to the gameplay changes made in Rune Classic.

DeepUnder1Odin <-Changed transition, restored exit geometry.
DeepUnder3 <-Changed transition, restored entry geometry.
Hel1 <-Restored entry geometry.
Hel1b <-Changed transition.
Hel3a <-Changed transition, restored entry geometry.
HelLift <-Changed transition, restored entry geometry.
Goblin1 <-Added Rune Classic (1.10) entry geometry.
Goblin2 <-Restored entry geometry.
ThorMap4A <-Changed transition, restored exit geometry.
THORmap6Loki <-Changed transition, restored exit geometry.
DwarfMap2 <-Changed transition, restored exit geometry.
