Sky Fortress is the fourth and final game in a series of promotional tie-in
games for a Taco Bell campaign revolving around a Taco Bell marketing brand
called Spy-Tek. The objective of this game is to take one of the four Tek Kids
on a mission to thwart an evil villain named Dr. Havok who has stolen an
eXperimental Aerial Aircraft Carrier, the XAA Carrier “Albatross”.

The player chooses from among the four Tek Kids to handle this aerial mission.
The gameplay consists of piloting a small jet craft through a cloudscape while
dodging enemies and collecting powerups along the way. The enemies include
flying monkeys and flying masks. Powerups include 2 different types of
weapons, fuel for your pod, and Taco Bell logos which restore your overall
health meter. There are also warps that give your pod an incredible speed
boost (but the warps do not grant invincibility, so you still need to dodge or
destroy enemies).

Another feature of the game allows the player to create a custom desktop
wallpaper by combining various Tek Kids against backgrounds chosen from the
various Flash Ops games, along with a Taco Bell “Think Outside The Bun” logo
in a customizable position.
