Page "Gamma World" Paragraph 13

The seventh version is a 4th Edition D & D genre setting using a modified version of the 4th Edition mechanics.

Instead of choosing a character class, a player must roll a twenty-sided die two times and consult an accompanying character origin table.

For example, a player might obtain the result " Radioactive Yeti " and gain the powers associated with the " Radioactive " and " Yeti " origins.

Two decks of cards are included with the game.

One deck represents random Alpha Mutations, which can be drawn to gain temporary powers, and the other contains various Omega Tech, powerful technological devices that could possibly backfire on those that use them.

Other deviations from the standard 4th Edition D & D rules include new damage types such as " Radiation ", Gamma World-specific skills, and increased lethality.

Despite these differences, it is possible to use characters and monsters from a D & D game in Gamma World and vice versa.
