Capcom has confirmed that Mega Man 11 will be out on Steam (and other platforms you may have heard of) on October 2, with a new "Double Gear System" that enables more powerful buster shots, the ability to slow time—or, if you dare, both at once. 

Both the Speed Gear, which makes the world move much slower relative to Mega Man, and the Power Gear, which boosts regular shoots and enables the Mega Buster to fire two shots at a time, can be switched on and off at will. But using them too much can cause Mega Man to overheat, leaving him unable to use the Double Gears until he cools down. Enabling them both at once is a particularly high-risk maneuver because that mode can't be switched off once activated, and Mega Man will be left very weak for a  period after it runs out.
