Mount Gundabad: Defend Nordri while he activates the ancient weapon
You can't let the Dwarves die. Quickly run on the left or right side of the wall to get to one of two crossbows. Use it - begin to shoot the enemies who are running inside through a large gate on the left. At first, there will only be goblins but soon orc warriors will join the battle...
...as well as heavy-armored orcs whom you need to kill with at least two crossbow shots. Keep eliminating the enemies and don't worry either about the Dwarves, or your companions - they should do just fine. After some time this stage of the fight will be over and your heroes will have a chat with the Dwarves.
The second stage will be much more difficult because of the trolls who will join the fight. To kill them you need as many as six cross-bow shots - so hurry and be accurate at the same time. It's best to shoot at enemies' heads. After killing the trolls start shooting orcs - heavy-armored and fighting with two weapons. Then kill the third troll.
After a while you will notice four trolls coming through the large gate. Try to shoot them as many times as you can before the enemies even start fighting with your allies. The trolls are your main target, so don't waste time on shooting goblins. It's likely that during this level you will unlock the [ACHIEVEMENT] War-machinist (elimination of 150 enemies with war machines in a single playthrough).
Once in a while, when no enemies are coming through the large gate, look around to find those who forced their way through. Archers are especially dangerous (they position themselves on the stairs on the other side). Before the next trolls' attack you'll have to quickly kill a large number of archers. Then start shooting trolls and orcs. When a message telling you that you've carried out the objective is displayed, the level will end soon. You will also unlock the [ACHIEVEMENT] Mountain-breaker.
