The most fun addition is utilising the One Ring, which grants you invincibility and unlimited combos, once you build up a meter by branding enough foes, that is. He can gain health by killing Orcs that he's branded, teleport, and so forth. Celebrimbor lands faster and more powerful shots with arrows, but cannot slow down time briefly. It's a good thing that Celebrimbor already has most of Talion's abilities and upgrades, too, though he does handle a bit differently than the Gondorian Ranger. While the difficulty levels out halfway through the experience, this will definitely scratch the itch of those who thought that the main game should've been more challenging. Planning strategies before entering a fight and familiarising yourself with all of the moves is essential.
Soaring at the highest levels and having more gruelling traits to boot, the Orcs are no pushovers since major battles will usually result in 20-30 enemies assaulting you with several captains in the chaotic brawl. While the primary objective of branding five Warchiefs to face Sauron sounds easy enough with Celebrimbor's immense power, you'll be shocked with how difficult it is to subdue them and their captains for the first two hours of gameplay.
