The first military encounter of Bydo Mission I, where the famous R-9A Arrowhead fought its first battle, and where it excelled. Entering through the main entrance of the stronghold, R-craft pilots will travel through a mechanical stronghold, containing many basic Bydo that will be encountered in later missions. This is a straightforward area; though strong with defensive units, it's far easier compared with later missions. However, the true challenge is at the end of the Encounter, where Dobkeratops awaits. This is quite a change from the small defensive Bydo seen previously. Defeating Dobkeratops will lead to the next stage in the mission, the Creature Cave.
