Payday 2 is a very well done game with the goal of pulling off heists whether it be banks or other valuables while co-operating with 3 team mates.
You are meant to survive waves of enemies which get progressively harder as time passes.

Time itself is precious and getting though the vault to the money as quickly as possible and a 180 seconds seams like ages when you are trying to keep your crew and yourself alive.

The music fits perfectly and was implemented at the right times of the heist, a mix of relaxation while waiting for someone to come through your sights while keeping an eye on the clock to make sure the drill is not jammed up again.
Guns act with higher recoil and do require more hits on the more armored targets but are satisfying to use.

Overall customization is incredible, though there is a huge ammount of items locked behind a dlc paywall, personally I like to buy my game up front rather than buying the base game and spending another 40 dollars on dlc.

In the end it is a very reccommended game especially if playing with friends.
