MAP32: Prestidigitation is the super secret level of Icarus: Alien Vanguard. The level takes place in a simulation of a mountainous area where various structures, including a lake, mysteriously appear as the level progresses. It was designed by Ty Halderman.
The word "prestidigitation" is a synonym for sleight of hand, and may be a reference to buildings and other things suddenly appearing in the outdoors portion of the level as if by magic.
After grabbing the red skull key, you have to shoot a target situated in a dark tunnel to open several walls in the main area and also an alcove to your north, revealing a spectre and an armor bonus. This same tunnel can be climbed into; do so and walk through the target to find a berserk pack (sector 108). Grabbing it opens the aforementioned alcove's back wall, releasing a chaingunner.
