Dynamic Crater
Craters are formed by explosive ordnance such as bombs and dynamite upon detonation. The larger the explosive, the larger the crater. For example, a bomb's explosion will leave a far bigger crater than dynamite.
Craters that are deep enough to reach sea level will fill with water. Otherwise, they will emit toxic smoke that causes suffocation damage.[1]
Craters can be cleared by using the circular button next to the demolish button on the Construction (F11
) window.
Craters can also be used strategically to reveal underground buildings or parts of buildings.
