Save One More is a heal'em up about the war of toy soldiers where you are going to save lives instead of taking them.
In Save One More you play as a combat medic trying to save as many lives as he can. Your squad will take part in different battles and stealth missions and without you there are no chances they can survive the war.
This is the game about war, but you will not make a single shot - your job is providing help to the wounded on the battlefield. You won't be able to save them all, so sometimes you have to choose who to save and is it worth of risking your own life. But a good medic does not leave anyone behind.
You have no direct control over your allies, but often they could use a push to the right direction so you can decide which path is safer for them. Some of your choices will define how the war ends for your comrades.
