This is a very complex game, so you need to get all the docs and cheat resources.
The game has docs (93 pages), commands (6 pages), tutorial (97 pages) built-in. You can access them using SHIFT+H, ALT+H, CTRL+H.
For printing, we also include the PDF versions. The Steam installer should do a silent install. If this fails for whatever reason (e.g. OS permissions), please follow this procedure to install them.
Look in the Steam's game install folder e.g.
C:\Program Files (x86)\SteamLibrary\SteamApps\common\Universal Combat CE v2.0
There you will see UCCE20_steam_shortcuts.exe
Please run that file to do a silent install of the docs and other resources (e.g. cheat codes!)
You can then locate this folder in Start/3000AD/Universal Combat v2.0 Docs
Also, the Engstrom class carrier, GCV-Starguard featured in this game, appears in our upcoming Line Of Defense game where you get to run around inside. More here.
