Empyrosis by Killin is fun on June 25, 2002
Empyrosis is a fairly complex siege map set in a volcanic environment. The attackers must first take out three solar panels located on the roof of the defender's main base. The destruction of the panels brings down the forcefields protecting two more generators, each located in peripheral towers near the main base. When the attackers destroy these generators, the forcefields protecting the main base come down, allowing access to a third generator. With this generator's destruction, more forcefields in the towers come down, allowing the attackers to destroy two generators.
