= Lotan's Tomb (Demo Version) =

Lotan's Tomb is a fork of Freedoom, a complete, playable set of
free/libre and open source game assets for the id Tech 1 engine.
It is made available under the modified BSD licence meaning that
anyone is free to share it, modify it and reuse parts of it,
subject to that licence's terms.

This is the plaintext manual for the demo version of Lotan's Tomb.
It contains only the most basic information and no hyperlinks,
illustrations or mechanics details.

This is not a "demo version" for a curious player, but rather a
stripped-down build designed to be used in technical demos of
adaptations of the Doom engine in machines with limited storage space
(if not quite as limited as shareware Doom allows).

If you just want to check out LT, please download the full version
of Lotan's Tomb and start Phase 1: Jailbreak instead.

Plot

Some time passes in your new home at the other edge of galactic
civilization. You decide to take a trip to some of the other worlds,
but unfortunately the war against American Galactic Ministrties and
their Third Pain Empire allies had been raging on without you.
The border guards ignore your documents and lock you up in their
tiny, shitty outpost jail pending who knows what.

But fortunately for you (and totally not for any reason you might have
manufactured) one day everybody's neural implants go haywire yet again
and one awful fugue state of chaos and destruction later you pick up
a gun from a nearby corpse and slowly begin to make your way out...
