Junkbot Undercover

In this sequel to Junkbot, our trash-eating hero discovers a conspiracy involving a mysterious "Project X" that every bot except him seems to be aware of. To unravel the mystery, Junkbot must collect the trash on each level of the factory until he has found enough discarded keycards to progress to the next floor underground. As the player, you must help Junkbot to navigate each level and collect the trash by moving LEGO bricks to build platforms and block hazards for him.

Junkbot walks constantly back and forth, changing direction only if a tall object or wide gap blocks his path. He can climb over objects that are one brick tall and jump over gaps that are one brick wide, but turns back when faced with taller or wider obstacles. If Junkbot touches a hazard or an enemy robot, the player loses the level.

Returning hazards that Junkbot must avoid are fire elements, dripping taps, and hostile enemy robots. All the puzzle elements from the first game, including fans, jump pads, and shield blocks, also make a return. New puzzle elements brought into the mix include deadly lasers and blocks that Junkbot can move just by walking into them.
