There are 3 different gamemodes in Mechanic Miner. It's possible to change gamemode upon creating a new game, but it's not possible to change gamemode on that specific game afterwards.
"A great way to learn all about this world through a compelling story line."
In Story Mode you will progress through different acts by completing quests. Furthermore a Story Mode game can be started with a tutorial teaching you the basic of Mechanic Miner. In Story Mode you'll start with a basic vehicle, some resources in your inventory and a few unlocked technologies.
Currently Mechanic Miner has one act to Story Mode (Act 1).
"Build and explore without restrictions."
"Advanced players will have a chance to prove themselves in this merciless End Game mode."
In Survival Mode you will start in a random generated world. It's up to you what you want to do, but survival is much harder in this gamemode. In Survival Mode you'll start with no resources and a few unlocked technologies.
Every now and then, an Aether Storm will appear, making all enemies aggressive towards the player while spawning Flying Demons and more Interceptors.
