The Strogg are ready however, and react by unleashing a massive EMP shock wave which disables these vessels, sending them and the marines inside plummeting to their deaths.
The invasion of Stroggos begins when countless individually manned drop pods are launched toward the planet's surface. Set concurrently with the events of Quake II, The Reckoning begins as the combined forces of Earth are set to counterattack an alien race of cyborg assimilators known as the Strogg. The Reckoning was developed by Xatrix Entertainment, who were best known previously for having created Redneck Rampage, a satirical shooter based on Ken Silverman's Build engine. It features a new single-player campaign composed of five units (in addition to seven new deathmach maps), and contains three new weapons and two new enemy types (as well as seven modified Quake II enemies). The story is once again set on Stroggos, though it follows a new protagonist known as Joker. Quake II: The Reckoning is the first of two official expansion packs for Quake II, id Software's popular action-oriented first person shooter.
