Combat in Army of Two is fast and consistently keeps you on your toes whether you are playing it alone or with a friend in both offline and online co-operative play mode. From the action-packed opening and the huge attack on the city of Shanghai, where buildings crumble around you and planes crash into the densely packed city, you have to keep your finger constantly on the trigger. The key component of Army of Two is working with your partner to take down enemies.
Using the directional buttons, you order your partner to stay behind cover, follow you or advance. Tapping each button twice triggers Aggro, wherein your partner will launch an attack on the enemy drawing their attention away from you, so you can sneak around and flank them. You also have an ample supply of firepower at your disposal including sniper rifles, machine guns, pistols, grenade launchers and rocket launchers.
Each one can be upgraded for better handling, damage and accuracy. Purchasing new weapons is simple; hold the Triangle button and select Weapon Customisation from the menu to be taken to a store jammed with new toys for you to pick and choose from depending on how much cash you have in your account. Completing objectives, saving hostages and looting downed enemies is the fastest way to top up your account so always take the time to do this. In Army of Two: The 40th Day, cash is your best friend.
