Collection of optional mods compatible with the Extended Tech Tree Mod (ETTM) by SirCampalot. This collection is a repository of optional mods that are either made as addons for Extended Tech Tree Mod or are mods made by me that have specific balance changes to the game.

While the primary Extended Tech Tree Mod Collection is a collection that are guaranteed to all work together, this collection is a repository of all the mods that are (usually) made by other mod authors as addons for Extended Tech Tree Mod. Some of these mods will require an additional mod to be used.

For example, there is a mod that makes Optimal Storage icons for Extended Tech Tree Mod, but this mod will require both ETTM and Optimal Storage.

Many of these mods require another 3rd party mod to function correctly. Please read the description of each individual mod listed here as they will often require another mod to function properly.

This collection will also list mods made by SirCampalot that will also work with ETTM, but I find otherwise not fitting enough for the main ETTM collection for one reason or another. Examples of this are the Tyberium mods (they are an obvious nudge towards the old Command and Conquer games and are thus less lore friendly) or Unlimited Manpower! (I use this mod all the time, but having an unlimited supply of meat for your meatgrinder may be seen as a sigificant departure from the base game).

Mods in this collection that are made by SirCampalot can be subscribed to, but may have significant impact on how the game is played.


I made this collection as I find it convenient to have these mods all in a single location and they should work with ETTM (and maybe 1 other 3rd party mod) and because I just found it annoying to have to do a search every time I wanted to reference them when asked about them.

If a mod listed here is no longer functioning properly anymore, please let me know and please also notify the respective mod authors.
