Door Kickers: Action Squad is a retro side-scrolling action game where you play as a SWAT agent dispatched to Nowhere City in the United States.

Choose your gear, then kick down the doors and get ready for action. React, adapt to the quarter turn and if necessary, do not hesitate to restart the game without thinking. Master your weapons' recoil and reload time, manage ranges, exploit cover, and use your strategic in-game abilities to use medkits or reloads at the right time, or decide if your teammate is worth to be saved. Unless you prefer to keep your points and release your ultimate move to finish the last room without too much difficulty.

And if it gets too hard for you, get a friend to help you.
