KONAMI

Enemy Alert Levels

Alert mode

This can be either in "infiltration" or "discovered" mode.

  • Infiltration mode
    The normal state, when the enemy has not discovered you.
  • Discovered mode
    The enemy goes into discovered mode when they spot you.
  • Back to infiltration mode

When Spotted by the Enemy

If you're discovered, enemies will storm you and start aggressively attacking. Try to avoid being spotted as you proceed.
If an enemy spots you, a "!" will appear, and they will attack. Defeat all enemies onscreen or move to the next screen to return to infiltration mode.
