During 6 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 6 rounds without going insane due to paranoia or dying due to ill-health, it will be time to see if you will be recognised 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 or your squad in good shape.
