ARMOUR PIERCING & ENERGY ARMOUR
Armour Piercing works against DR, but does not work against the Light or Heavy energy Armour of the Predators.

BLINDSIGHT vs INVISIBILITY
Blindsight works to target Invisible figures at range, but does not allow targeting through Forest or Particle Terrain.

COMBAT CHANGE: COVER & TARGETING (See SWM Rules)
A character can attack an enemy with cover only if it’s the nearest enemy.  Even if the attacker can attack the enemy with cover, the enemy gets a +4 bonus to its AC for cover.  Terrain and characters provide cover, an adjacent enemy never has cover.

DIAGONAL CORNERS
Diagonal Corners can be moved through without penalty, but are not legal positions to stop on.

ENERGY EQUIPMENT
Energy Equipment becomes inactive when a figure with it moves through SHALLOW WATER, WATER, DEEP WATER or PARTICLE AREAS (Dust/Fog/Steam) until their next activation.

LOW WALL (Gray in Colour)
Low Walls can only be passed by figures with Flight, adjacent figures with a low wall between them are not considered threatening, flanking or in melee with one another.

MORALE RULES
In AVP Morale Rules apply, it is assumed that when you run away off of the board, you run to your doom. Figures may attempt to Rally even if not under Command.

MAP ICONS:
DIFFICULT TERRAIN as per the rules in the DDM rulebook.
FOREST as per the rules in the DDM rulebook.
This is HIGH GROUND, it gives anyone on it +2 to hit against anyone it can legally target that is not also on high ground. These can only be accessed by figures with flight or by access points (like a ladder). Characters on HIGH GROUND have line of sight and can be targeted over a LOW WALL they are adjacent to. A figure may move normally when moving off of High Ground terrain.
This is a LADDER, it allows access to a diamond location for anyone without flight, but makes them slow for the rest of their turn as per the slow rules. If a figure has done an action and then moves to the Ladder, they may not ascend it until their next activation.
NARROW PASSAGES are represented by green lines within solid black squares. Entrances and exits are marked by circles, they may be exited/entered in any open adjacent squares. A figure moving on to an entrance/exit moves immediately to another connected entrance/exit as a swift action.
PARTICLE AREAS (Dust/Fog/Steam). These areas block line of sight as per the rules and also affect energy equipment listed above.
SPIKE STONE as per the rules in the DDM rulebook.
