Will there be various ending states or slides, like in Fallout, or is this a do or die affair? What assets will be available to gather intelligence on your foe? Snitches, beggars, upstanding citizens doing their civic duty, that one honest bobby etc. I have to admit that I do like the inclusion of scouting out the opposition, makes imminent sense, and is rarely utilised in games.
Hey, sorry for the slow response, Nonek. In terms of ending, it's likely that there will be 2 endings, depending on how much mayhem you cause - there's a choice between using lethal force for extra damage, or non lethal force, and allowing the police to take it from there. Surveillance is abstracted a little - you pick a city tile, and either go yourself, or send an ally to see what they can find. First you have to figure out if there's criminal activity in the tile, and if so, which gang is responsible. After that you can launch a mission against that tile. Higher levels of surveillance are required for finding allies, gang leaders, and enemy facilities.
