PHost has extensive support for add-on programs. Add-ons can heavily change the behaviour of the game. For example, there are add-ons which allow you to move minefields, to destroy planets, or to transport starship components with freighters. All rules in this document (and the rest of the documentation) are valid only for standard PHost, use them with care if add-ons are in the game.

See Manipulating the Host Sequence.

This is a testing version.
It may be incomplete, and have more bugs (or features) than the public live version at planetscentral.com.
