Though back when i did these i thought, i just need proof-of-concept to get this off the ground, alas not even that far did this thing get to before i lost interest.
I actually had an old colleague work on this with me (programmer) but we lost touch and well - its not the first failed game project on the web, and it sure wont be the last.
So im posting the screens here just so they dont rot on my HDD :P
A little about the game,
It sorted started out as a genuine attempt to just bring an old classic up to date, the idea was to create basically an HD version of X-COM.
It then progressed to the point where i was convinced that THIS is the next thing for people, even after the announcement of the new x.com (fps game afaik) people still cry out for a genuine follow up to the 1993 game - which essentially was 3 games in one.
My idea then was to take the old game and build on top of it, not to change anything, but to widen its scope - add more objectives, update its style (3d but low poly and using pixel art-like textures).
And furthermore i wanted to add a whole new basebuilding part, gone would be the top-down view and just setting up bland bases.
Nope, now the player would be in the drivers seat of how the base really looked - main inspiration came from tycoon games such as hospital tycoon and theme hospital, where the player engages in gameplay where you're supposed to build facilities to accomodate different objectives.
This would add a whole new dimension on top of the strategy, you would gain insight into what your alien containment really looked like - essentially adding more micro-management to a game already full of it (granted it would be lessened in some areas).
I also had an idea of merging the 'terror from the deep' games with UFO, essentially granting gameplay possibilites on both land and underwater which could've been quite cool i think.
....dammit i still want to finish this though! :S
EDIT: found some more old sketches
