In Agent of Descend, you have to guide Secret Agent John Doe down the elevator shaft and deep into a building crowded by the city's most dangerous criminals. Stop on each floor and take out the crooks. They're all intent on gunning down or stabbing your agent, so make sure your weapon is fully loaded and your equipment is upgraded and ready for use. Each deeper level will feature a small army of increasingly strong, armed thugs. How far will you be able to get before they overwhelm you? Try to upgrade your gear and your character strategically. You can come back up the elevator shaft when things get too intense.
