As The_Spoon would say...
Description:
In my project, I aim to create an edition of every level of the campaign so that 2 players can play co-operatively to beat the campaign. But also to add a few of my own ideas in there too!

Features:
- A save/load code system found in ORPGs to record items/abilities between levels.
- Score system, where at the end of the level you get a grade A-E, based on how well you did.
- The interludes are incorperated into the map, so you don't have to download a seperate map to watch a video.
- Original heroes for when there is only 1 hero on the level.
- All the levels will be set to 'hard mode', but with help from your team-mate it should all be reasonably possible
- Shared research and techtree systems with your ally.
