The Beast(Days of Ruin) or Gate of Steel(Dark Conflict) is the ninth mission in Advance Wars: Days of Ruin and introduces the player to the airport and the Rig.
News that Isabella is infected has reached the Mayor of Freehaven, who is very unhappy with this and demands that she be removed. Brenner, however, strongly refuses to leave anyone behind. Meanwhile, Will wants to see Isabella, but Dr. Morris can't allow it, but informs Will that because of him, she wishes to live despite most victims desiring euthanization.
On their way to the Seratta mountain range, The Beast launches a large scale attack on the 12th Battalion.

The sheer number advantage the Beast has seems intimidating, but the Beast isn't exactly the smartest person in this situation. Most of his units are on the ground and on the other side of the sea, while most of your units are high air units, rendering most of the Beast's forces useless. Nonetheless you need to pick your targets wisely. You have only a handful of infantry to capture cities but be careful not to get them within range of the enemy's rockets as you cannot make more infantry. Target the only Duster the Beast has, and if you can, try to eliminate the Anti-Air while not within the Missiles range. Otherwise, avoid them entirely and focus on destroying their rockets and battle copters to build up veterancy. With so many units to destroy, you'll need to resupply, so have a Rig nearby at all times, and this will merely be a tedious battle.
