The series is an early example of open-ended , non-linear gameplay. They lack a predetermined story path, but the player is instead given the choice of what missions to follow in whichever order while being able to visit almost any place in the game world at any time from the beginning. The ending can be determined by the player, who can alter the ending through their actions, can complete the game at almost any time, and continue playing the game even after the ending. Some of the games give the player the freedom to complete the game almost immediately after starting it, particularly Metal Saga , which could be completed with a full ending scenario just minutes into the game, making it the shortest possible RPG. The character classes , such as a mechanic or soldier, could be chosen for the player characters , who would fight in turn-based battles either on foot or using tanks and other vehicles such as motors. The player could create tanks, customize and make a variety of modifications to them, remodel and enhance each part, strengthen the defence, repair damaged parts, and give them more shells .
