Good news, managed to replace the load screen, rename level names in the menu and finished the GATE A ending. The game mod will be semi-linear with sandbox level areas with non-linear levels(not like Mirror's Edge's campaign) if I won't play with the level save stuffs. Lots of rooms have already been made. Will try to make it as close to the original CB... I will try to experiment more with modifying game files (don't really care about the base game, since everything is replaced).
Edit: Added custom bot templates, making MTFs will be 500% easier to make.
Edit2:
