"Invasion Strategy" is a solid-state pinball machine released by Komputer Dynamics in 1975. This head-to-head game allows two players to compete simultaneously from opposite ends of the playfield, each controlling four flippers facing their opponent. The playfield features six pop bumpers and two spinning targets, with both players launching balls simultaneously. Players can achieve objectives that disable their opponent's upper flippers and devalue their bumpers, adding strategic depth to the gameplay. The machine's unique design and competitive elements make it a distinctive entry in the pinball landscape of the mid-1970s.
