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.
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. They have powerful attacks, allowing them to do high damage to the enemy. They can also be used to light the Explosive Mines , potentially causing an end to the enemy base. However, Berserkers can be targeted and killed easily with their low health. Therefore, they need a meat shield of other units to cover them. Then, in battle, use small groups of them to strike at key points in the enemy forces (like heroes). They shouldn't be used against archers or cavalry as the range and trample of these units can be used to kill the Berserkers before they can do anything. Overall, Uruk Berserkers need to microed carefully, but can be a deadly weapon in the hands of the right player.
