The August issue of PC Gamer magazine is packed with a preview disc featuring a brand new look at as-yet unannounced Protoss units for StarCraft II. The new units include the Soul Hunter, a mechanized ground unit, the Phase Cannon, a teleporting version of the Photon Cannon, the Tempest, the next evolution of the Protoss Carrier and the Twilight Archon which appears to be analogous to the original game's Dark Archon. There's also a painfully brief gameplay sequence, showing off additional units.
