Agent Decker is a mission-based deck-building game for one player in which you acquire gear and skills by facing obstacles. The alarm raises every turn, so you must pick who you take out. Do you go for the cool weapon, or take out the security camera? Each mission takes about 20 minutes, and the game consists of five missions that are meant to be played in sequence. There's also a high score system, so you can try to beat your own best runs or compare your score against other players!
