New GDI units. Their variety of weapons works on just about anything, making them a formidable enemy. Spider-like, their web launchers temporarily disable infantry, while dual cluster missile cannons are equally effective against buildings and vehicles. And to top it all off, they heal fast in tiberium deposits. GDI players will fear these.
Limpet drones bury themselves beneath the ground, and clamp on to passing enemy vehicles.
This can be useful for infiltrating cloaked bases, but seems really to have been included to fulfil mission objectives in the single player game Both sides have gained mobile war factories, and although they are slow-moving and must be deployed before building, they provide a way to reinforce armies at a battlefield level. They are vulnerable, though, but useful if combined with Nod's new mobile stealth generator. Nod's powerful Reaper GDI drop pods come as an addition to the Upgrade Centre. These contain five elite infantry squads which can be deposited anywhere on the map. They make a good suicide squad for taking out enemy power plants, but seem to be no more use than the existing ion cannon.
