Hacx keys

Hacx keys function roughly the same as in Doom, opening doors and activating switches that require their usage. While the Z-keys are analog to Doom's skull keys, the other three are objects which can more loosely be defined as keys: a blue security keycard, a folder with a red mark containing a password, and a large Sigma, the 18th letter of the Greek alphabet (Σ). The latter is typically found in cyberspace levels in Hacx.
