|Secondary Representation||Ape Escape|
The match starts on two ISA Intruder platforms descending to the planet surface of Helghan. After time has passed, the Intruders will drop off the combatants onto the Helghan battlefield. After a few missiles destroy part the area, a few Pipo Monkeys can be seen running around, and Specter piloting a Goliath appears. The stage then transforms into a more tropical setting and the Goliath proceeds to destroy the Arc Towers, then turns its attention to the players. At the very end of the match, it appears that the Goliath is destroyed by the ISA.
