A Giant must test to see whether it falls over if any of the following apply:
If it is beaten in close combat. Test once results are established but before taking a Break test.
If it is fleeing at the start of the Movement phase.
When it crosses an obstacle. Test when the obstacle is reached.
If the Giant decides to Jump Up and Down on an enemy. Test immediately beforehand.
To see if a Giant falls over roll a D6. On a roll of 1, the Giant falls over. A slain Giant falls over automatically.
To determine in which direction the Giant falls, roll a scatter dice. Place the large template in base contact with the Giant in the direction of the scatter dice, measured from the centre of the Giant's base. A model hit by the falling Giant suffers 3D6 S 8 Hits that have Multiple Wounds (D6), though no single model may suffer more than 1 Hit – any excess Hits are ignored. If the unit is in combat and the Giant has fallen over whilst attempting to Jump Up and Down, wounds inflicted by a falling Giant count towards the combat result.
A Giant that falls over automatically suffers 1 wound. If the Giant is in combat then this wound counts towards combat resolution.
Once on the ground a Giant may get up in his following Movement phase, but may not move that turn. Whilst on the ground a Giant may not attack, but he can still defend himself after a fashion so the enemy must still roll to score hits on him. If forced to flee whilst on the ground the Giant is slain. If the Giant gets the opportunity to pursue his foes whilst he's on the ground he stands up instead. A Giant may attack in close combat as usual on the turn he stands up..
