Terrain Effects


There are three main types of effects for terrain types: water, ice, and toxic waste.

The water terrain effect prevents zombies from crossing, but doesn't prevent the player or bears from crossing.

The ice terrain effect prevents polar bears from crossing (because they have an irrational fear of the ice breaking beneath them),
but not the player or zombies from crossing.

The toxic waste terrain effect will prevent the player from crossing (because he would get radiation poisoning), but doesn't prevent zombies from crossing.
