Relive the unwavering mission of a soldier who refused to surrender.

Recreate the experiences of soldier Hiroo Onoda during his stay on Lubang Island — thirty years of adventures, danger, comical situations and tragic moments, life and death and, above all, a demonstration of the resilience of human beings in adverse conditions — in the solitaire game Onoda.

During six rounds of variable duration, you have to obtain a number of resources that will allow you to finish the turn without suffering penalties. In each round, you will also undertake a mission, earning honor points for it. During your adventures, you will experience some of the events that the real-life Onoda had during his stay in Lubang. If you manage to overcome the six rounds without going insane due to paranoia or dying due to ill health, it will be time to see whether you will be recognized a hero or fade into oblivion.

Onoda will get different results depending on the amount of honor you have accumulated solving missions, keeping your comrades alive, and keeping your squad in good shape.
