As of 2018.10 the LPG articles are still a WIP. If you have a question that isn't answered, or a topic you'd like to see added, we'd like to hear about it. Post your thoughts on the Talk:Learning to Play the Game (LPG) page.


In this lesson we'll teach you how to shoot around corners! How to make free strikes disappear! And magic...! No not really.

Shooting out your arse[edit]

Here's the rule that you need to follow:

Determining LOS (pg 39 of rulebook pdf)

  1. Draw a straight line from any part of Model A’s volume to any part of Model B’s volume that is within Model A’s front arc.
  2. The line must not pass through a terrain feature that blocks line of sight.
  3. Step 3 & 4 are not really relevant to this lesson.

Since you can draw LOS from any part of Model A, there is absolutely nothing wrong with starting it at your arse. As long as the end point (at Model B) is within your front arc then you're good to go. Clever positioning will let you shoot around corners, as shown in the diagram on the right.

Left Arc, Right Arc ... I'm the guy with the gun[edit]

In addition to the LOS rules quoted above, huge-based models have additional rules for left and right attacks.

Huge-Based Models & Line of Sight (pg 40 of rulebook pdf)
A huge-based model’s front arc is marked on its base. Its front arc is further divided into two 90° fields of fire. These fields of fire determine which models a huge-based model can target with its weapons, depending on the location of those weapons. Weapons located on a huge-based model’s left side (L) can be used to target only models in its left field of fire, and weapons located on its right side (R) can be used to target only models in its right field of fire. Weapons with locations “S,” “H,” or “—” can be used to target models in either field of fire. If any part of a model’s base is on the line separating the left and right fields of fire, the model is considered to be in both fields of fire.

The thing is, LOS isn't tied to firing arcs. That is, determining which enemy models are in your LOS (and so can be targeted), and choosing which weapon will target which enemy, are two separate steps.

In the example, even though the target is completely "hidden" from the righthand guns, the colossal can shoot it "through" the building anyway.

Free Strikes - Disappearing Act[edit]

Here's the rule that you need to follow:

Free Strikes (pg 44 of rulebook pdf)
When an engaged model advances out of an enemy’s melee range or line of sight, the enemy model can make a free strike against it just before it leaves.

The loophole here is, you can get out of the free striker's LOS without advancing. What you need to do is advance a different model between the attacker and the model that you don't want to take a free strike. However, this will normally take more than one "chaff model" so it's only worth doing if the original model is a "high value" model that you can't afford to take a free strike. For example, a warcaster who has only 1 hitpoint left.
