Getting back into the fight

[kineas]

I couldn't find explicit download links for you. You can get the links from this page: https://www.shrapnelgames.com/Camo_Works..._page.html

The main game download will start automatically by opening this page: https://www.shrapnelgames.com/Demos/FV_MBT.html

It seems to me this downloads version 6.0, then you need to apply several patches to this version:

http://www.shrapnelgames.com/Patches/PD_MBT_11.html
http://www.shrapnelgames.com/Patches/PD_MBT_12.html

but please double check.

This was the free version. The full version is available from their store, that might need patching as well.
Similar procedure for the ww2 game.
