Any ship can choose the Intercept mission in order to attempt to move to the same point as another starship. To do so, the player must be able to "see" the target ship on the starmap and have the intercepting ship target it before selecting the Intercept mission.
Intercepting takes place during the Intercept phase of the movement stage of Host. The three major movement phases of the Host are:
Since Hyperjumps take place during the normal ("Move Most") move phase, intercepting ships can successfully target them for intercept. However, since the Firecloud Chunnel takes place after all movement, intercepting a Chunnelling starship will normally leave the intercepting ship at the target's pre-Chunnel location. Likewise, as Cloaking takes place before any movement, a successful cloak will cause the intercept attempt to fail; a failed or interrupted cloak remains vulnerable. A ship with a failed Intercept mission will not move at all, regardless of waypoint settings.
It is important to note that Intercepting ships move in turn, by increasing order of Starship ID #. Therefore, a low-numbered starship set to intercept a higher-numbered ship that is also moving during the intercept phase will move first, ending (if possible) at the initial start point of its target. The higher-numbered ship will move later, and this movement will not be affected by the presence of the first starship.
A ship set to Warp 0 and Intercept will not move (of course), but the waypoint will be set to the last recorded sighting of the target. If the target has cloaked, moved via Chunnel, or was not visible to the player at the beginning of the turn, the Intercept mission will fizzle with no effect.
