I recently purchased Treemagik G3 and PlantLife. Those applications generate low poly trees, plants and rocks, so they are ideal for touching up the game maps. Treemagik is great, but PlantLife is a bit buggy and doesn't have as many options as Treemagik.
I started off with the Canyon map, you can see the before and after shots below.
I've also decided to release the TTW Map Editor. It allows the easy creation of maps and missions for Total Tactical Warfare. So if any of you create a nice map I'll be sure to include it in the next release :)
I've reimplemented the main menu using Windows Presentation Foundation (WPF). The problem with the old menu was that it was very slow and sluggish. The new one renders using DirectX, which makes it lightning fast. WPF also allows the use of styles and other effects to make the menu look better.
Timbo made two more insurgent skins. Have a look at them in the screenshots below.
Llamalord, Timbo and myself also added some more props: aircon, generator and satellite dish(skinned by timbo) and water tank(modeled by llamalord & skinned by me).
