Wolfenstein 3D:the Unit-731 outbreak
Plot(just and idea so far):The year is 1942 during the Second Sino-war of world war 2. A series of documents leaked to the Chinese National Revolutionary Army reveils a secret project the Empire of Japan is working on to give them an edge in the war. Shiro Ishii, the commander of the human expermentation lab Unit-731 in Harbin, China is planning to make an army of genetically engeneered super mutants for the Japanese Imperial Army to help their aggression throughout East-Asia. The worst it is an experimental genesplicing modification(last boss ues it) that turns it's users into deformed combat abominations.
Nazi Germany and Soviet Russia, two counties acting as a foreign supplier of the Chinese National Revolutionary Army receives a message requesting a large supply of artillery, air planes, munitions, etc... in to further arm their troops for an operation to lead a massive attack against the Empire of Japan and take Unit-731 and in exchange promises to give Germany all the data the National Revolutionary Army finds in Unit-731. The operation was called Operation Bio Terror.
In an attempt to kill two birds with one stone the United States has sent in you. You are B.J. Blazkowicz. Known for your countless victories of single handedly fighting the the Third Reich of Nazi Germany you know that you are now needed elsewhere. Your mission is clear.
Assist the National Revolutionary Army as a mercinary during their campaign, reach Unit-731 with them, gather all the documents before they can, and blow the place up preventing neither the Empire of Japan, the Soviety Union, or Nazi Germany from being able to create an army of mutants.
Note:This is just what i've thought of so far.
Japanese soldier:The backbone of the Japanese Imperial Army, these bastards come in 3 A.I. forms. The traditional kind which approched the player and shoots him and the duck and cover approch in which the AI is tweaked for them to position themselves behind a 3D block, pop out, and shoot at the player. The third is stationary. Shooting at the player, standing idle, and then shooting at the player again. Uses the death grunt sounds the human enemies from Turok Dinosaur Hunter use.
Suicide bomber:Remember the suicide bombing clones from Spear Resurrection? These basards are like them by running up to the player and blowing themselves up. The difference here is that the have a charge attack which allows them to sprint at the player in a straight line toward the player while not flintching from damage.
Jeep:Basically a Japanese jeep with a mounted machinegunner. These foes can only go forward, backword, or diagonal. Not left or right. Easily destroyed by missiles.
Tank:Like the jeep, but tougher and with a cannon. They can't move left or right(only up, down, or diagonally) and are best taken out with a missile.
Truck:A truck carrying a load of Japanese soldiers. The appear when the player approches a trigger that causes them to move in a scripted destination on the field and park themselves so the soldiers can get off. A truck is really just 8 3D blocks put together to form a truck. The blocks move along to their scripted destination sometimes smashing a gate/fence in the process(this has been done in the mod Death Trigger, so I know this is possible).
Zombie:Mutated victims of Shiro Ishii's mutant virus. Unlike other enemies which are activated by sound these guys can only activated by either seeing the player or walking over an event trigger. The don't flintch when getting shot meaning players must shoot at them while moving backwards.
Zombie arm blade men:Experimental mutants from Unit-731. Like the zombies, but their have a built in shield on one hand and a blade on the other. They can only be hit when close to the player since that's when they remove their shields from their chest.
Demoniod:These genetically engeneered humanoid creature fight much like the zombies, except they are far faster and can take much more damage with their sharp claws. They also don;t finch when shot. Most dangerious is their forward jump attack which thrusts their bodies forward, slashing the player.
Ape trooper:Armed with a arm missile launcher, these ape like creatures attack by firing three missile(much like the cyberdemon from Doom). There's a delay before they do, so you can take cover.
Venom Spitter:These giant spiders with tenticle like arms appear in mining tunnels aswell as other underground areas. The attack by spitting acid at the player. However their attack has limited range as the acid falls to the floor.
Worm nest:Encountered in enclosed spaces, these creatures attack by spitting clustered of paracitic worms at the player that chase the player for a few seconds. The die however so taking potshots at these guys is essencial.
A cliff level where the player shoot enemy on the side of a cliff. Eventually leads to a river dam.
A level taking place during a flood where the water causes you to drown. In this level you'll navigate using the roof tops.
A sewer boss level where where there a massive room consisting of sewer water(done using the highwall effects which are explained later). A masssive system of rail ways are contructed throughout. Eventually the boss will show up by poping out of the water. The boss is a gaint octopus that uses two attacks which he seems to use at the same time. The first is a tenticle sweep in which a tenticle will pop out of the water next to the railway(this is done by having each tenticle consisting of multiple sprites. Kinda like a an Snes/Genesis game). The second is the acid spray attack which requires players to look at the boss while they are running from the tenticle to avoid. The gaint octopus uses the same sound as the Gonarch from Half Life and looks much like the Leviathan(the octopus boss) from Splatterhouse 2. Music used in this level(it starts once the boss appears):
New special effects:
The game would be done using a uniquely modified Wolfenstein 3D source code allows manipulate virtually anything like the Zdoom engine.
Exploding 3D blocks:Certian 3D blocks can disappear uppon the players approch can disappear with granted has been been done in Orb of Dilaaria, but here when they do fire and debris spits out in various directions indicating them being destroyed by an explosive. Used numerous times for enemy intro's(espeically tanks).
Buttomless pits. You may notice how some Wolfenstein 3D mods have skies, but what about the ablity to apply that to the floor. In additon to buttomless pits 3d speical effects are made to make the buttomless pits have walls at the side(a cliff for example).
Highwall effects:Many levels that use the outdoor atmospehere effect will also have atmospehere's rendered in 3D to give the player the illusion that certain walls are bigger than they actually are. However the height of the wall very allowing for more freedom to decorate levels.
Intro animations:many enemies might have intro animations. For example:Japanese soldiers might jump through a hole in the ceiling in buildings.
Multiple death animations:Many enemies will have multiple death animations each done smoothly.
The game will not only use gun bobbing when players are using, but also screen bobbing in which the screen bobs up and down when players are moving(There's a Wolfenstein 3D mod called Death Trigger which allows you to look up and down. Might be a good place to start).
All gun shots from enemy will emite a spark. You may remember how in Castle Totenkopf SDL Edition used this feature. Here the game uses those sparks on every shot an enemy makes.
Blood splat sprites not only appear when enemies are shot, but are also used excessively when an enemy is killed. For example:A Japanese soldier holds his neck will have blood sprites gushing from it.
Ladders. Using speical effects walking up to a labber will activate a cutscene in first person to give the player the illusion that they are climbing the ladder in the in game engine.
Enemies are fully animated.
10 guns and 7 ammo types. The game limits how much ammo you have forcing players to switch between weapons constantly.
Both in game cut scenes(shown from a different view point than the ground during gameplay) and between level cutscenes which are a parody of the classic Neo Geo arcade game Nam-1975.
Music mostly from the Turok N64 games.
While the game uses the Wolfenstein 3D engine, it is modified to play more like Turok Dinosaur Hunter do to how everything would be designed. For example:the player moves slower, but it's still done in a way that allows player to dodge particles.
A level where you steal a tank. This level would be like the beginning of level 2 in which you can destroy buildings, obsticals, and such. It would use the "Texas Slave Fortress" level music from Battle Tanx Global Assualt.
