The Berserkers were even larger, more ferocious versions of the Uruk-hai; they were the most powerful members of Saruman's army. It is said that, before battle, their helmets were filled with blood. The smell drove them into a blood frenzy and they had no concern for personal safety. They are the strongest Uruks of Isengard and have the ability to detonate Explosive Mines.
An Uruk Berserker has 2000 base health.
While not a clearly stated ability, the Uruk Berserker can also be combined with a Siege Ladder before they are set against walls. The Berserker will climb to the top of the ladder where he will remain until the ladder is positioned against a castle wall. Only then will the Berserker leave the ladder. This can be a useful strategy for clearing an enemy castle wall of archers and allow other infantry to climb the ladder in peace. If the ladder is destroyed while a Berserker is riding it, the Berserker will die as well.
The Uruk Berserker can be given the following upgrade:
- Other infantry if they are swordsmen
- Monsters and Cavalry if they are pikemen
- Buildings if they are cavalry
The Forged Blades upgrade can be made even more effective by researching the appropriate upgrade at Isengard's unique Outpost expansion, the Steelworks.
Uruk Berserkers are a late-game unit that can be recruited from a Level 3 Uruk Pit. Similarly to the Beornings, they should be used to support the other Uruk-hai. While they do boast a lot of health points, they generally are not as powerful in the Edain Mod as they are in the base game. Uruk Berserkers are significantly weaker, running at the same speed as normal infantry, attacking without splash damage, dealing a lot less damage overall, and having a poor armor rating. They can still regenerate health at level 2 and onward, but their armor rating is so low that it isn't really worth it. Unless you have Saruman with his Power of Speech ready on the field, don't expect to see a berserker live beyond the first level of veterancy.
As they are a unique soldier in Isengard's army, berserkers should be recruited and managed carefully, as their main purpose is to deal slightly heavier damage to specific targets, such as enemy heroes and monsters, while the main forces protect them from undue harm. They are also among the few units that can set off an explosive mine, provided it has been placed and not prematurely destroyed. While an Uruk berserker may give off an impression of being a mighty engine of destruction, you're really better off spending resources on upgrading your normal soldiers instead.
