does anyone no if there will be a competitive multiplayer (not co-op) kinda like call of duty using tht as an example

Yes but not like cod, this is not cod, theres multiplayer which is resistance vs security. Its team vs team not free for all, please actually read about brink before asking un-needed questions

singleplayer, co op and online are all together, playing co op is the same as single player and multiplayer only diffrence is that multiplayer the enemy are human players and yout yeamates are human players, co op is against ai opponents and your teammates are human players and bots if theres not a full team, single player is just you against bots and your team are bots. Gameplay for the most part is the same.
