There will not be a series of linear missions. Instead the player will be in command of a mercenary unit and choose between missions across the Inner Sphere.
Around 300 planets in the Inner Sphere will be open for business, "letting you travel between the Great Houses while taking increasingly demanding contracts and building reputation with each faction as you also manage your lances of warriors and supporting technicians."
The timeline will progress, with new technologies becoming available and the Clans arriving.
You start the game with one weak Mech and work your way up.
Mech customization will be very limited (if at all possible). The game will feature more than 60 chassis with 300 to 400 variants.
In different parts of the Inner Sphere, different Mechs will be for sale.
There will also be different weapon manufacturers.
The build played the the PCGamer writer did not include any free market aspects.
The damage model has been improved. There are different stages of armor peeling away until the internal structure begins to show.
There will be infantry, artillery, land and air vehicles.
The maps for the 300 planets will be dynamically generated. Some parameters: density of foliage, terrain patterns, weather, time of day.
