Page "Quake 4" Paragraph 8

After performing a number of tasks, such as destroying and capturing Strogg aircraft hangars and defense systems, Kane and his remaining squad members make it to the USS Hannibal.

There they are given their next mission: infiltrating one of the Strogg's central communication hubs, the Tetranode, with an electromagnetic pulse bomb in the hope that it will put the main Strogg Nexus in disarray.

Kane is tasked with defending the mission convoy, which takes heavy casualties.

After many setbacks, including the destruction of the EMP device by a Strogg ambush, Kane is left to complete the mission, assisted only by Private Johann Strauss and Lance Corporal Nikolai " Sledge " Slidjonovitch.

Strauss figures out a way to destroy the core by shutting down its coolant systems.

As Kane reaches the entrance to the Tetranode, however, he is greeted by two rocket-equipped network guardians – as well as the newly constructed Makron.

The Makron easily defeats Kane and knocks him unconscious.
