Counter-intelligence (CI) projects counter the effects of enemy Intel projects. An incoming Intel project first encounters the rightmost CI project. If that's not enough to stop it, it continues right to left until the cumulative CI points stop it, or it burns through all CI projects and succeeds. It makes no difference if the CI points are all in one project or spread over 12. Level 3 CI is more effective than Level 2 which is more effective than Level 1. If a CI project "fills up" it ends and the points in it are wasted. Put such a project into queue position 12 and direct points to another CI project or to offensive Intel.

In my current solo game, I started with 3 CI Level 2 projects and a few hundred points per turn. When the Narn hit me with several Intel projects, the first ones failed but subsequent attacks burned through my CI. As I built more Intel facilities, I was able to defeat all Narn Intel attempts. When I researched advanced Intel, I directed my points into CI Level 3 projects and put my old Level 2 projects at the end of the queue. Now the AIs are gradually burning through the Level 2 projects and will eventually come up against the newer Level 3 defenses.
