Earth

Ten level episode for the game engine, ZDOOM. This episode fully accomodates ZDoom's enhancements of free-look, jumping and the Boom/ZDoom enhanced set of line specials. It also has areas of complexity and grandeur of archetecture and settings not previously possible under DoomII. EarthZD also has a custom sky specifically designed for ZDoom. It is based upon the Earth.wad episode for DoomII by the same author.

Story Line You arrive home in Earth's planetary system exhausted from enduring vicious combat that started on Phobos and led to the Gates of Hell.

You study your options and decide to insert upon a remote and rocky coastline. Levels: The Ruins (MAP01): You stand at your point of arrival, facing out to sea with rolling breakers splasing on the rocks. This looks like it should have been your vacation site.

Combat These levels contain a wide variety of combat situations requiring different strategies. To win these levels, especially at the more difficult skill settings, requires thinking in terms of fields of fire, planning your cover, looking out for your flanks and backside, and keeping open your lines of retreat. Most of the monster placement is randomized so that their location and response are different each time these levels are played. Hence, you will be unable to count on finding specific monsters at specific locations. (And there will not be many opportunities for blasting monsters in their sleep.) The monsters occasionally show sneaky behavior due to features in the level designs. Setting: This episode is set on a rocky coastline. with spectacular outdoor views. These include high vistas and overlooks, live surf crashing onto the rocks, scenic elevator rides on the outside of tall buildings, spectacular bridges and a spectacular hilltop fortress new to EarthZD. General: Secrets generally have some clue that the thoughtful and observant player can spot. These levels are designed to be winnable at the easier skill settings without finding the secrets, but to win the more difficult settings requires locating most of the secrets. There are no totally hidden hazards or traps; there will always be some visual or audio cue to warn of there presence. Some of the pools and slime pits have depth, ie, you will sink into them, sometimes up to your eyeballs. Remember, though, this is ZDoom with free-look and jumping that plays more like Quake than the original Doom. Objects like trees, barrels, etc., are not infinitely tall and the player can jump up onto objects as tall as 56 units; this will be an important factor in navigating some places and finding some secrets. One final note; cliff edges at most of the high vistas are lethal to fall off of (one cannot expect to survive a fall of several hundred feet in real life).
