In Central America, rebel forces are battling Union troops for control
of Chiapas. But the guerrilla struggle becomes an interstellar war when
a lethal energy sliver from the Maw crashes into the Mexican
jungle... pursued by the Maelstrom's most vicious aliens. Now in the
fallout, a wounded Shard is mutating into a horde of crystalline
monsters, while an undead Pharon priest slaughters both Union and rebel
soldiers to reinforce his zombie army. And as the fighting escalates
into bloody anarchy, the deadly energies build and intensify,
threatening a damnation worse than even the Maelstrom itself...
