Scourge from the Deep (3e)
What you are holding does not fall easily into any one category of Hero Games supplements. In the world of Champions¸ the unusual is often commonplace. In some cases¸ the most unusual thing is the environment itself. Have you ever been in the midst of GM-ing a battle or a chase sequence when one of your Players says¸ "I'll run to the edge of the pier and dive into the water.." Previously¸ there was no easy way to continue the battle beneath the waves. The HERO rules do not include guidelines for handling underwater combat¸ and until now¸ every GM was left at the mercy of his players. No longer.
