Learn the best CO and unit strategy for Technique 83/100 in Advance Wars 2: Black Hole Rising, focusing on mountain traversal and defeating Hachi.
Walkthrough
- 1Choose your Commanding Officer (CO) carefully based on the map. For maps with many mountains and narrow passages, limited cities, and no airports or seaports, COs like Max, Kanbei, Colin, and Green Earth COs are less ideal due to Hachi's low costs and the need for units that can traverse mountains.
- 2Foot soldiers are essential for crossing mountains. Prioritize building powerful infantry and, more importantly, Mechs.
- 3Sami and Sensei are viable options, but Lash is recommended for her "terrain attack bonus."
- 4Build infantry units to capture the left-hand silos.
- 5Follow up with Mechs and Recons, then add Artillery and Rockets.
- 6Build one unit specifically to take damage and act as a blockade.
- 7When Hachi is nearing his CO Power (approximately 3/4 of his last power star), attack him relentlessly to force him to wait for his Super Power.
- 8As Hachi gets close to his Super Power, ensure any cities he might capture are covered, then attack him to make him waste it.
Tips
- Focus on units that can handle mountainous terrain, especially infantry and mechs.
- Lash's "terrain attack bonus" is particularly useful on maps with significant elevation changes.
- Use a sacrificial unit to control enemy movement and create blockades.
- Timing your attacks to disrupt Hachi's CO Power usage is crucial for success.
