Upon starting Advance Wars 1+2: Re-Boot Camp, players will have access to just four COs in the War Room, Online, and Versus game modes. Specifically, those COs are Andy, Max, Sami, and Olaf, though they are certainly not the only officers in the game. Indeed, there are a myriad of unlockable COs in Advance Wars 1+2: Re-Boot Camp, and this guide contains full details on how to obtain them.

Before getting into the specifics of unlocking each of the COs, it is worth mentioning that the overall process is much easier than it is in the original releases of Advance Wars 1 and 2. This is, in large part, due to the fact that the paths through the campaigns have been simplified, and players no longer need to fulfill specific requirements in order to access the Sonja missions. Additionally, missions that were not played during a campaign become selectable upon beating its final mission, making it quite easy to target specific COs and reach 100% campaign completion.

In summary, players that are interested in unlocking all the COs should put their efforts toward completing every mission in both of the campaigns. As previously noted, this is much easier to do in the remake than it is in the original releases, which do not allow fans to select unplayed missions at the end of their campaigns. Furthermore, every CO can be unlocked on Advance Wars 1+2: Re-Boot Camp's Casual difficulty setting, making the road to obtain all of them even less arduous.

One final thing to note is that Advance Wars 1+2: Re-Boot Camp players will need to purchase the COs from Hachi's Shop after fulfilling the unlock requirements that are indicated above. While this process may already be clear to some fans, it is being mentioned here for the sake of completeness.

Advance Wars 1+2: Re-Boot Camp is available now on Nintendo Switch.
