House Rules

Movement

 * Infantry climbing onto rooftops use 3 inches of their movement to scale the building
 * Jump (when using their jump packs), Jet pack, Jet bike, and skimmer can move onto buildings at no vertical movement cost
 * They do have to take a dangerous terrain test when landing on rooftops but not when jumping down

Cover

 * Aegis defense lines and walls are 4+
 * Aegis defense lines and walls count as two way cover (saves for both incoming and outgoing fire) unless the majority of a unit is within 3 inches of the wall (the unit counts as crouching behind the wall firing over it) and the enemy doesn't receive a cover save from the wall anymore.
 * If the majority of both units are within 3 inches of a wall or aegis line (backs against the wall shooting blindly into the mass of units hiding on the other side) then they both get a 6+ from shooting.
 * Trees and equivalent are 5+
 * Being on a roof gives a 5+ unless the attacker is also on a roof, then it's a 6+
 * Tank traps, barb wire, and equivalent are 6+

Retreating and Unit Retention
The goal of this persistent campaign is to not throw away your troops every battle in all-or-nothing fights that exist in a vacuum. As such, you will be able to retreat units off the field. Any unit that retreats of its own will (read: not falling back due to a failed morale check, they die as they leave the field) or are in reserve count as having survived the match.

You must retreat towards your own board edge.

If you are losing a match or forsee the death of a very important unit, it could be wise to make a tactical retreat and save what you can. You will need it for Week 4.

Addendum: If the game ends and a unit(s) is falling back due to morale, they count as having survived the match, since they are not off the board and therefore "destroyed" as per 40k rules.

Remember! Keep track of the losses/surviving MODELS, not units! Keep notes on which particular models survived.

Addendem: If your warlord retreats manually off the field, since it denies Slay the Warlord to the opponent, it awards the opponent a STW victory point. The benefit to running off the field is saving your unit for week 4+.
