These House Rules Modify the Standard Rules.
While a PC pilot is in his battlemech, he is considered to have the ‘Toughness’ Advantage.
Toughness: The PC has a exceptional resistance to physical abuse. He makes Consciousness Rolls (in Mech combat) with 3d6, using the best two.
NPC and enemy Mech Pilots in battlemechs must make Consciousness checks as do PC characters do to avoid passing out.
This is to correct that it is easier for Enemy mechs to make their Consciousness checks than it is for PC characters.
Ammo and Weapon Jams
Mechs with Ammo Fed Weapons may carry a mix of appropriate ammo types. The type of ammo loaded may be changed with a simple action.
Example: if a weapon type can carry Regular or Inferno rounds, you may change the type of round if you have loaded the mech weapon with those rounds.
Ammo Fed Weapons may Jam in Combat. After making a to-hit roll with a result of a natural 2, roll 2D6. On a result of 11+ the weapon jams and cannot be fired again in this battle.
In order to add a new item or redesign a mech, a successful roll of Technician/BattleMech and Engineering must be made. Make a Natural roll of 2D6.
