Marvel Cinematic Universe - Mod for ZH
The concept:A conversion mod for ZH with three new factions: S.H.I.E.L.D., Hydra, and the Avengers.
S.H.I.E.L.D. is relatively simple - Use the conventional base and faction mechanics.
The Avengers will take some balancing - A Tower (and maybe a warehouse or two for cash) that produces the heroes and upgrades and unlocks as the game progresses to make them stronger as the conventional teams get stronger.
Hydra will probably be a mix of conventional and custom mechanics. Defiantly using the cut defector power to show double agents and probably a barracks purchasing mercs.
