Red Gate Bridge

Red Gate Bridge is a Tag Team Stage in Sonic Forces. The level starts out with Sonic and the Avatar running across a smaller bridge to find Metal Sonic, who was sighted in the area by Resistance forces. As the duo crosses the bridge, a Death Egg Robot Sentinel smashes the bridge beneath their feet. They land on a ledge, looking at the robot. Perform a Homing/Wire Attack to initiate a Quick-Time Event. If successful, the pair will Homing Attack the robot through the head, destroying it. The two will fall into a pit, where they collect some rings and a White Wisp capsule. Proceeding further will initiate the http://sonic.wikia.com/wiki/Metal_Sonic_(Sonic_Forces) boss fight. If you want to read about the boss fight, just copy and paste the link above, as I don't know how to make hyperlinks. Sorry for the inconvenienc, and I hope someone comes to clean it up.
