In TT, the Engine could take three hits before being destroyed. The weapon that hit it didn't matter, if you rolled an Engine Crit, it took 1 hit. Three little circles on the record sheet for "Engine Hits." Each Engine Hit caused you to generate 5 extra heat per turn, so with two engine crits, 10 heat per turn; three engine hits, mech disabled.
IS XL Engines take up three spaces in the left and right torso. If a side torso is destroyed, the engine takes three hits, and is destroyed.
Clan XL Engines take up only two spaces in the left and right torso, so only takes two engine hits from a side torso destruction - which will only destroy the engine if it already had another engine crit previously.
There be the actual rules, as I recall them.
Thats not how it works in MWO.
In MWO the engine, just like any other component has a HP value. Most components have 10hp. The Engine has 15hp. When you strike an internal location, you have a 42% chance to deal damage to a component. This is split further into a 1x, 2x, or 3x critical hit. Meaning a medium laser that does a 3x hit will deal 15 damage to one of the components.
This means a Gauss Rifle hitting an exposed torso, left, center, or right, has a 42% to destroy the mech outright. As it stands now, all engines have 15hp. This does NOT mean 15hp per location, the engine itself has 15hp period. Clan mechs unless they change how engines are destroyed WILL be destroyed on a Left or Right torso critical hit from weapons fire. In addition the engine IS destroyed when any of its slots are destroyed.
The amount of slots in a left or right torso, under MWO mechanics means any XL, clan or IS, will be destroyed upon a left or right torso destruction. The TT rules for three hits and its out doesn't apply in MWO.
Now this might change in the future. But I have a sneaky suspicion that it might not.
