Tiberium Dusk is a re-imagining of the Kane's Wrath universe in a way I feel better fits canon, as EA did a pretty poor job with the C&C franchise continuity from Tiberium Wars onwards. This mod doesn't change anything with regards to the story but helps add elements to the gameplay that "fill the gaps" and provide a more Tiberian Sun esque experience (including all its flaws and unbalances) and departs away from the Kane's Wrath RTS formula. Still a work in progress, I've made changes to the AI (buffed turtle AI and made brutals harder), made changes to "Militant Squads" which make them work with the timeline of the franchise, changed the "Nod" faction entirely with a new name, as Kane's Wrath "Nod" works more of a splinter faction rather than a true "Brotherhood"; with Marked of Kane being the new face of the faction. There are also numerous changes to GDI and Scrin, especially Reaper 17 and Steel Talons, which make them play significantly differently.
Video of the new "Classic Commando", I may do a demonstration of the Ghost Stalker as well, but the classic commando's changes are quite pronounced and only really visible in a video.
Essentially, he's stealthed whilst not fighting; wields a slightly more effective silenced sniper rifle. (And it is actually silenced, as its only audible directly above the firing position, and thus can't be heard as easily as other sounds ingame)
He's also faster than other GDI commandos by 10 units per tic, and he has 25% less health to make up for his insane stealth ability.
As seen in the video its fairly effective even against the AI which can magically detect stealth units so he's a pretty potent commando.
