Wikipedia wrote:It is considered to be a successor to Tom Clancy's Rainbow 6: Patriots, which has been cancelled. Like all other titles in the series, it will focus heavily on team play and realism. However, there are major differences to older versions of the game, featuring a heavy multiplayer focus and destructible environments. A trailer at E3 2014 demonstrated a hostage rescue scenario and the game has initially received positive reactions.
At the E3 demonstration we saw an example of multi-player teamplay in a "Hostage Release" mode. Players formed two 5 person teams: "Team Raven" were the attacking Rainbow 6 police type SWAT team who had to enter a large suburban house to rescue a hostage; "Team Rogue" were the defending hostage takers who fortified the house to prevent the SWAT team escorting the hostage to safety. After each 5 minute round the player team swap roles. For the SWAT team there seems to be primary weapon sets depending on selected roles in the team: 2 with sub-machine guns / assault carbines with suppressor; one with ballistic shield and pistol; one with a shotgun; one was a sniper who located outside the house. The Rainbow 6 team have flash grenades; breaching charges which can blow holes in walls and ceilings and a number of surveillance drones which can be deployed before the round starts to locate the hostage or during the match. The Rainbow Six team members could "vote" between different entry points e.g. garage or roof - rope down from a helicopter. The hostage takers can choose different locations for the hostage's initial location. The defenders use the pre-match time to reinforce the structure of the walls, block windows and doors by screens, place rolls of razor wire, plant explosive booby traps. The hostage takers seem to have a range of shotguns, sub-machine guns, pistols, can throw C4 explosive charges, can deploy moveable bullet proof shields. Team members and the hostage can be given first aid if wounded.
Time is a big issue and the priority is to release or keep hold of the hostage for five minutes or to kill all the enemy team. More gameplay types will be revealed in the final game but the developers say that all combat will be urban / interior Close Quarter Battle (CQB).
