Sentry Trap

The Sentry Trap (DK2), Artillery Trap (DKO), or Cannon Trap (DKM), is a cannon.
==Dungeon Keeper 2==
The Sentry Trap is also known as the Magic Missile Trap. It is an automated, rotating cannon that fires at any enemies within its range. It is one of the more basic traps in Dungeon Keeper 2, dealing minimal damage. While single Sentry Traps are ineffective, a battery of them, combined with ways to keep the opponent away (such a Barricades, Freeze or Fear Traps), can be a powerful force.
Despite its minimalistic damage, Sentry Traps have the longest effective range of any buildable trap in the game, and unlike many others, will function until destroyed. The only other ranged trap, the Lightning Trap, has a much lower rate of fire than the sentry trap and is generally less cost-effective in terms of damage unless the opponent is on water. If engaged by a possessed creature, however, the velocity of their projectiles is fairly low and can easily be dodged, especially at long range.
===Hero Sentry Trap===
Like other traps and doors in Dungeon Keeper 2, there is a hero variant. While functioning the same, the Hero Sentry looks more like a traditional cannon, featuring wheels either side.
==Dungeon Keeper Online==
The Artillery Trap was seemingly the equivalent of Dungeon Keeper 2's Sentry Trap.

===Overview===
===Notes===
*Fired cannon balls at range.
*Could fire in multiple directions.
*Visible trap.
*Maximum number allowed increased by upgrading the Workshop.
*Overall maximum available is six at level 10, three of which were available after the tutorial. More became available at higher levels.
*Fired cannon balls travel until they hit a minion or a wall.
*Surprisingly, cannon balls passed through rooms, traps, Doors and Reinforcd Walls. However, everything but rooms still blocked Cannon "line of view", so it wouldn't attack targets behind such cover.
