A combat round lasts as for an interval of time the GM defines. A character may opt to hold his or her action, but loses it if he or she waits past the end of the round. Characters may dodge one and only one attack instead of attacking. All others are applied against the character's Dex. Attacks are made.
Damage is applied.
GMs should define how much damage weapons used in their campaign do. Hit locations are not defined here either, for simplicity, though such systems may be used with these rules. In some games, armor or other protection subtracts from damage applied. The GAME is obviously only a bare skeleton of mechanics, and leaves most of the fleshing out to the GM and players. It is meant to be a tool to be used for improvisation and impromptu gaming.
