What i did not mentioned when i wrote the news about the game is that you this game has allies.In the beginning of the game and in the demo,at the firing range you saw three more "prototypes".They will be you allies in the game during your first objective and will follow you everywhere.
You cannot give them commands like "Cover me" or "Stick together" but there will be sounds during the game which changes the ambient of the game.
They cannot crouch to pass under the objects or jump as far as i saw.
They will only crouch when waiting for you to move.
