Barrier

 is a unit. It's a small, inexpensive, prompt defender that dies after one turn.

Strategy
Being Prompt and costing very little, Barrier is useful as a small defender for situations where you only need 1 more defense and thus buying a Wall or Aegis would be wasteful. Buying several Barriers is usually preferable to buying a smaller number of Forcefields since the Barriers do not require Drone sacrifices; however, holding a Drone and buying a Barrier is far worse than buying a Forcefield (it's essentially the same thing except it costs more). As Barrier is not particularly efficient soak even by base set standards (Wall is slightly better), it should not be your main source of defense, but should instead act mostly as a green sink.

Also, like other blockers with Lifespan, Barrier has counters.
