iGuerilla is a challenging first person shooter game. The game offers two different control modes where you can use the accelerometer or touch based commands in order to aim and shoot. Your weapon reloads automatically but you also have the option of shaking the iPhone itself. The game requires 1 shot for a head shot kill, 2 shots to the body for a kill, and 4 shots to the arms and legs for a kill. This made the levels somewhat difficult when being attacked by multiple enemies from far away and became a little frustrating. You also earn money by different types of kills.
There are hidden weapons and survival briefcases in each of the 9 combat areas which you must capture in order to make it through the higher levels without dieing. Game difficulty is also set on 4 different levels: rookie, sergeant, veteran, and hero.
