6. Red Orchestra 2: Heroes of Stalingrad
There are a lot of different types of World War II first person shooters out there, but ones that focus more on realism are typically not as prevalent in the medium. However, developer Tripwire Interactive changed that with Red Orchestra 2: Heroes of Stalingrad which is a multiplayer focused title that rewards smart players. Users not only have account for bullet drop and spin, but have their entire HUD removed, forcing them to check their ammo manually.
This style was a sharp contrast to other military shooters like Battlefield and Call of Duty which focused more on an arcade style of gameplay. Thankfully, Red Orchestra 2’s focus on realism really helped it stand out, which was only enhanced by the great level design, weapons, and attention to detail.
