In another thread, I suggested giving Andro bases the cloak instead of the temporal elevator. I think that is about as close as you can come in SFC.
Basically, it's a time rift that the bases could create around themselves that made seeking weapons take longer to reach the base. The bases moved themselves further away from you in time rather than in position. The weapons would take several impulses to cross that last hex rather than just one, and plasmas would thus run themselves out without going anywhere. Only, the rules make it a lot more complicated than that. Those Andros were weird.
