Jet & Missles - from the QuakeLab

Jet & Missles - from the QuakeLab or Jet with Missles - from The QuakeLab is a Single Player level.

Walkthrough
You spawn in a river of Water with land to your right. On the ground are 2 Enforcers guarding a Door, some Crates, and a few Radioactive Containers. Move slightly to your right, towards the middle of the area. A message will appear, stating "Air support ETA 5 sec. Do not engage!".

After five seconds, a jet will fly across the level, blowing up the area with the Enforcers. The Crates will be destroyed, the Radioactive Containers will be blown up, the Door will be blasted open, and all that will remain is a row of fire. The message "Perimeter defenses destroyed." will be displayed as all this occurs. Kill the Enforcers if they were not killed by the explosions.

Glitches

 * Due to the heavily scripted nature of the level, it is relatively easy to break the sequence by doing something the level did not anticipate. For example, avoiding the trigger by hugging the wall can result in the player reaching the platform without assistance from the jet.
 * The Crates blow up by proximity detection of the player or jet, meaning the player can blow up the Crates before the jet even appears by reaching the platform before it.
 * To compensate for the missed trigger, the jet will often appear after the player reaches the platform, albeit without a warning message.
