GM Diaries #3: The Plot Unveiled

The Heroes tangle with the gang of thugs at the mall, only to find many of them surprisingly resilient. It gets stranger when they start throwing blasts of lightning around, leaping twenty feet up, and growing metallic claws. The heroes manage to defeat or chase off all of the gangsters, and are left with the puzzle of where these powers came from. It seems apparent that they are somehow technological, but it's technology like nothing that's been seen before on earth.

One of the heroes tracks one of the runaways down, and interrogates him. He finds out that a lot of the local gangs have recently been buying "upgrades" from a shady clinic run out of a warehouse.

When they approach the warehouse, it appears to simply be a normal, if sparsely stocked, warehouse. A little investigation, however, reveals that the boxes and crates are holograms, and as soon as someone walks into the middle of the room, they are attacked, the illusion disappearing, revealing two squads of alien shock troops with advanced weaponry and a desire to keep their secrets.
