Doom press release beta

This beta version of Doom was released October 4, 1993. It was apparently released to journalists to trial the game before its release. The beta is time sensitive and will not start after October 31, 1993. It also has a "password" where the user must add the command line "-pressrelease" when running Doom.

The press release beta is similar in features to the final release of Doom. Some differences are:
 * Messages are displayed inside the status bar. When an object is picked up, the status bar changes briefly to display the message, before switching back.
 * The chaingun appears different.
 * The rocket launcher fires much slower.
 * The plasma rifle appears slightly different and fires the same ammo as the BFG 2704
 * The BFG 2704 is included (instead of the BFG 9000)
 * The lost soul has different graphics and attacks differently.
 * Different items: some items which appear include the demonic dagger, skull chest and unholy bible.
 * Elevators move much slower.
 * The map displays pictures of the weapons owned and a score (scoring was eventually removed before the final release)

Cheats
Several cheats were included with the documentation for the beta:


 * tst: Behaves similar to the iddqd cheat (God mode)
 * eek: Behaves similar to the iddt cheat (displays entire map)
 * amo: Behaves similar to the idkfa cheat (gives all weapons, ammo and keys)
 * nc: Behaves similar to the idspispopd cheat (no clipping mode)

Levels
Three levels are included. These eventually became E1M2, E2M2 and E3M5.
