Engine Cores

Fusion engines are defined by their engine rating. In BTA3062, engine cores are used as replaceable equipment allowing the player to increase or decrease the overall size and power of an engine. The larger the engine core, the faster the 'Mech moves. Note that some 'Mechs are limited to a certain engine core range depending on their size. As an example, a 20t Locust cannot fit anything larger than a 195 core.

For 'Mechs, their maximum walking momentum is directly proportional to engine rating. For instance, a 30-ton Spider BattleMech with a 240 Pitban Fusion Engine is able to generate the same maximum momentum of a 60-ton Merlin with the same engine, but because the Merlin masses twice the Spider, the Spider's maximum velocity is twice that of the Merlin.
