myself and 3 others battling Nashira during the open beta of darkspore.
this was at threat level 3-4, they made 3-4 endless play meaning we could chain as many levels as possible together for increased difficulty.
on release endless play will only be available when you complete 18-4 (the final level).
NOTE: we did outgear this level.
