Please no more hero's that are COMPLETELY useless by the end of the game. Its annoying to keep your hero in the back... the whole fight... just so you don't lose... Or at LEAST make them more durable.
Something that would be fun are minigame type levels that spread the virus across country borders. Country's would close borders if there was an infection and it would be fun to help them get from place to place by plane/boat or just pole vaulting over a wall. Just an idea.
