The following rules are optional, and can be used by players to add extra detail and tactics to their games. You do not have to use all of the advanced rules, you can use some and not others if you wish.

A Titan's commander may opt to forego firing in order to use its reserves of power to gain additional speed. This is called Overcharging. Declare before the Titan moves that it is overcharging its engines. A Titan that has overcharged its engines may double its Speed (note it's MAN stays the same). A Titan which has overcharged its engines may not shoot or use any weapons in the same turn.

Titans with void shields can protect each other by merging their shields together. This is a popular way of helping badly damaged comrades in the middle of a firefight. To merge shields, the two Titans must be in base-to-base contact with each other. Simply add the number of remaining void shields each Titan has together to see how many void shields are protecting them. If all the void shields are knocked down then the Titans can be targeted individually as normal.

Normally shooting into close combat is not allowed. However, some reckless commanders have been desperate enough to try this tactic to help an outmatched ally. Titans in close combat count as having their shields merged as above. If you wish to shoot into a close combat, roll to hit as normal. However, for each hit scored, randomise which of the combatants is hit (i.e. two Titans fighting, 1-3 is the enemy Titan, 4-6 the friendly Titan) then resolve damage as normal!

A Titan commander can divert power from the weapons to the damage repair systems, thereby increasing the chances of recovering. The Titan may not move or shoot but may re-roll any failed repair roll that turn - no roll may be re-rolled more than once, even if the second roll is also a failure.

Shooting at enemies at extreme close range calls for a cool head and confidence more than real accuracy. If a Titan is firing at a target within 15cm, use the Titan's CCS to resolve the to hit roll needed, rather than it Gunnery value. The weapon's accuracy and other modifiers apply as normal. You may point blank fire at a close combat opponent if you are in contact with an enemy in the shooting phase. Note that this is an exception to the normal restriction on shooting whilst in close combat, and like close combat attacks void shields do not protect the target.

A Titan can go onto overwatch to wait for an enemy to present itself, directing all power to the weapons so that they can fire at a moment's notice. At the end of any turn a Titan can go onto overwatch for the next turn. During the next turn the Titan cannot move or turn at all in the movement or assault movement phases, but can fire during any part of the turn, rather than in the shooting phase. You can even interrupt your opponent’s turn to fire. This means that the Titan could target an enemy as it moves from cover to cover, or wait until after close combat to see if there is an available target. However, you cannot interrupt your opponent once they have started rolling dice to resolve an action – for example if your enemy has made successful to hit rolls for a Titan you cannot try and destroy it before damage rolls are made!

It is possible for a Titan's princeps to direct more power to the void shield generators to sustain them against a determined attack. While this can greatly increase the Titan's chances of survival, the Princeps also risks burning the VSGs out completely. Whenever a void shield is knocked down you may choose to overload it. Roll a dice. On a roll of a 3 or more the void shield remains operational, on a roll of a 1 or 2 all of the Titan's VSGs are blown for the rest of the battle, just as if they had suffered catastrophic damage.
