Here's some Makaqu 1.2 screenshots:
VMU saves with different colored borders for each mod.
Super shotgun in action.
New grenade model. The skin is a recolored version of the hi-res skin from q1test. Some other models were also improved.
Non-solid skies. This is actually a QC workaround, and only works with the original maps because it depends on some BSP models included in Makaqu's PAK10.PAK file.
Additive rendering.
Additive rendering is also supported on static entities.
Translucent viewmodel over translucent water.
Stippled viewmodel over stippled water.
Translucent liquids.
