I'm moving out relatively soon and discovered an old backup CD of IW from 2003, back when it was still on the DOS Eduke 2.0 (I made somewhat regular backups of IW, but since months often went by before I worked on it again I never really needed to make frequent backups)
I don't even REMEMBER some of these plans and ideas, especially the creature transformation one. But in anycase you can see how the plotline differs from the released IW.
But in anycase, behold!
ROLL ON TOMMOROW
Time Zones
N/A (2004)
Objectives
-Reach the Docks; something has happened.....
HYDRO MEMORIES
Time Zones
Construction Zone in 1998.
Hydro Water base in 2004.
Magma Plant in 2016 (After Apocalypse (AA) )
Objectives
-Change Blueprints in 1998 so a particular wall isn't built in 2004
-Stop Water flow so Magma doesn't replace it in 2016
-Destroy Morphis Power node
METAL FUTURE
Time Zones
Ancient Japan in 1200
Neo Tokyo in 2004
Wastelands in 2016 (AA)
Objectives
-Destroy Tree in 1200 so It isn't turned into Metal replacement in 2004
-Destroy Statue so it isn't blocking path in 2016
-Activate Shelter roof so radiation isn't coming in + Can reach end target.
ONE KING
Timezones
WW2 in 1942
Town under siege in 2004
Memorial in 2016
Objectives
-Use Panzer tank to destroy Building
-Gather seeds of plant from Ruins
-Plant it near the Pillar & Find a Portal
Notes
-The Plant is significant as it will grow into a tree in 2018, which you will see after the Final battle
-Name is based on 3 Kings, which itself is a variation of Kelly's Heroes, in which a group of soldiers in WW2 plot a scam to get Gold. Or something like that, it's been a very long time since I saw that film
CIRCUIT BREAKER
Timezones
Stone Rain in Imagination world (2003)
Plant Ruins in (After Island exploded in IW) 2004
Trapped in Lava flow in 2016 (AA)
Objectives
-Stop Self from Blowing up Oil tanks (By Placing Barriers in Position), which resulted in Vital power being cut.
-Restablish control with the Construction bots, who will finish the Airship for use in 2016
-Free Airship from Lava & Pilot it outa there
THE EPION
Timezones
N/A (In 2016)
All levels will start in this ship in 2016 Time period from now on
Objectives
-Find out what happened in 2015
Notes
-We find out who Morphis is here. He basically takes advantage of the apocalypse & takes over Earth. Not that there's much to rule over. Anyways Revalion is now cruising the skies destroying anything & everything it sees. When the player reads this message, a motion detector behind them goes off reporting that a VERY large object is heading towards the ship. It's just a hunk of rubbish, but still... >=)
RED ENIGMA
Timezones
Crypt in 600
Raver club in 2004
Cultist Palace in 2016
Objectives
-Stop Alter from being Constructed (Which was turned into Turntable, which blocks way into Back room)
-Destroy Loud Speaker System (Used as Propeganda for the Cultists)
-Blow up Morphis' Statue
A REVELATION....
Timezones
Garmid 2004
The Apocalypse in 2015
Revalion's Crater in 2016
Objectives
-Head to Time Portal
-Witness Apocalypse, Survive & Than find portal to 2004
-Turn on Dormant Defense Functions in Main Control, than return to ship in 2016.
Notes
-Turning on the dormant defence functions won't help Garmid at all, however it will protect the Lower landing bays
& the Tunnel to Revalion's Lair. This will let you get to him in the next level...
LEGENDARY BATTLE
Timezones
Revalion's Crater in 2016
The Apocalypse in 2015
Earth's core in 2004
Objectives
-Destroy Revalion
-Fight & Kill Morphis
Notes
-To clear this up: Go to Revalion's Crater, Go back in time to the apocalypse & destroy it before it fully awakens. Revalion exists in all times at once, so if it dies in one time, it dies in another. However, when it is not active it is indestructible, & when it is awakend it is invincible. So the only way to kill it is to travel to a time when it is inbetween these stages & fight it. Finally, go to the Earth's core in 2004 & kill Morphis so he can't affect any of your actions (IE: Put an unbreakable Barrier on Revalion's lair, Kill you .etc) BUT!.....Before he bites the big one a shot of pure energy is fired from his body from Earth into the depths of space. A derelict ship picks this beam up as a homing beacon, & heads towards Earth; trouble is it can't stop, therefore 6 months after IW v2.0 it crashes into Earth! This is where my other add-on Survival begins! But was it accidental, or did Morphis have this as a backup plan? Better yet, is James to blame? Had he not killed Morphis, would the ship not of crashed into Earth? Bah, this is a Plan file, so I won't answer that here

EXTRA LEVELS
(If I can add more than 11 levels to Episode 4, these will be plans for some of them)
SOMEPLACE ELSEWHERE
Timezones
James' Home in 2003
James' old Home (Albeit in better Condition) in 2004
Ruins in 2016
Objectives
-Find a portal back to 2003
-Kill Gimpy before they damage your home (This is prior to the events in IW)
-Collect all the artifacts from the secret room in 2004, then go back to 2016
Notes
-Name is a parody of 'Someplace Else', a bloody great Half-life add-on.
GUT INSTINCT
Timezones
The Epion in 2004
Revalion's Insides in 2016
Objectives
-Jump off the Epion into a Timeportal in the sky
-Navigate your way through Revalion's Stomach & Pull it's plug
Notes
-Kinda gross this one...Revalion's stomach will be made of Lava & a Metalic fleshy substance. It's White Blood cells will probably be someform of Evil creature. The Player will fight their way to it's heart, but get knocked back into a portal by it's blood.
SECRET LEVELS
(Just a bunch of ideas)
HOLOTECH

Laser war area in 1998 (You know those crappy Laser Tag arena thingys)

SPRAYPAINT
When in the past, if you have a can of Spraypaint you can spray a message on a wall
& get points for it!
SPIRIT POINTS
Once you have the Spirit goggle Mod chip for the IR goggles, you can pick up spirit points. Get 100 of these,
& you can use James' Hidden power & Transform into a Xalonias (Invincible, Super fast, can fire energy beams & use close combat)
note from 2011 James: I honestly don't remember writing this idea, since it seems pretty far out there. It was probably my idea of a replacement for the steroid item.KOOKY HELPER GUY
Occasionaly the kooky shopkeeper will be hiding around the levels, if you find him he'll give you either some Rockets or a Medpak, the player can press 'Insert' to cycle between them (A visual indicator appears over the Shopkeeper's head showing them their choice)
