While very laggy the engine is actually done. The game could be played in its current state and any necessary tweaks could easily be done at a later date with minimal effort. I will start building the story mode next week and I think that will take about 2 months to do. Then I will need an extra month for the remake of the original mode which should be pretty straight forward.
Once both story modes are running fine and tested I will proceed to building Survival mode and establishing the extra content mode base. Once Survival is complete, tested and running with a few maps the game will be ready for release. So its about 4-5 months work if i go at a steady pace so expect a late autumn release date.
As for the Extra Content mode I will add stuff to that overtime but the game may have to be re-downloaded and I can't promise you will be able to rescue your save files.
