I called it an Orange Box Mod since it works on ALL orange box games and got ported for the Orange Box back in 2008, which is why the old HL2 commands do not work anymore. The game is also free now since TF2 is free, and you only need an Orange Box game to make this work.

This is shogun 2 total war if battle into a samurai army japanese empire is samurai shogun 2 all begins.

Its a HL2 Souce mod not Orange Box, Orange Box is the name for a Package deal

to move around in *

That game is not free though + not fast paced as BG2, and imo feels a bit more clumsy to move about with, but its probably since im not used to it.

also Mount & Musket for Mount & Blade: Warband for multiplayer Napoleonic goodness.
