Barrier

Barriers are extremely dangerous defensive devices that appear in Catacomb Armageddon and Catacomb Apocalypse

In Catacomb Armageddon


Developed by Nemesis's minions, both as a security device to keep would-be heroes out, and to keep dangerous monsters in, these devious devices generate powerful electrical shocks. In addition to preventing enemies from moving past, a Barrier can also inflict terrifying damage on the player if they try to bypass it, bringing low even a player at 100% health in a little over a second! They can be identified from afar by the arcs of energy jumping between the emitter posts.

Fortunately, Barriers can work to the player's advantage; monsters cannot cross a Barrier at all. They can also be destroyed, by either firing off Magick Missiles or Xterminators or Zappers at one.

A barrier has the equivalent of 20 hit points. They first appear in The Demon Hold, where the player will need to destroy them in order to progress.

In Catacomb Apocalypse
Fittingly for a Catacomb game that involves traipsing through time, Barriers reappear in Catacomb Apocalypse, in The Ancient Node of Time, where they are used to keep Nemesis' stockpile of Blue Demons on lockdown. They are just as devastating as they were in Armageddon and have the same amount of HP (20).

They're actually a little more beneficial to the player in Apocalypse, because they block the Wizards' line of fire.
