Free for all, death match, sandbox is about right for 2.2 and previous versions of RP2... although it did have a zombie mod in 1.4, but that was long ago now.
It is still on the C&C Renegade engine and that is why they covered it I am sure, in addition they realize that anything RP2 makes can (with a little extra work perhaps), be moved and deployed onto a stock Renegade map. The AI in this video are doing more than just a car following the road around the map; they start off as soldiers, wonder around the map until they have enough money to buy a vehicle, then once they have acquired a vehicle they follow the roads. There are parts of this AI that are evaluating targets to decide if they are enemy, the AI investigates sounds, selects different weapons for certain threats. The end goal of the AI is to simulate a player (even if it’s a n00b player); however I'm not going to deny that with a bit of work, the AI could be changed to repair buildings, attack enemy bases, and do other things that a player would do in a stock C&C Renegade round. So, if you need a reason that this relates to Renegade, that is the best one I can give for you.
As for goal of the mod, it is going to have more objective in 2.3 and will have the following game mods:
*Cops Verses Robbers (Player vs. AI cops where you have to capture and hold hideouts while also stealing loot to score).
*Free For all (pretty much the same as current but improved weapon/vehicle power/speed balance).
*And one other that I am still planning...
