Left for dead

The difficulty changes as you play. The game throws tougher, more numerous foes at dominant survivors and offers periods of respite or more frequent resupply to beleaguered teams. You carry one primary weapon, like a shotgun or assault rifle, as well as one (or two) pistols with unlimited ammunition. You can also pick up pipe bombs and molotov cocktails, which are each fantastically deadly in their own unique ways. These powerful explosives, along with primary weapon ammo and health boosts, are vital to your survival. However, supplies are often hidden in rooms that are slightly off the beaten path, and slowing down to explore more areas will put you at higher risk for a zombie attack. This risk-reward element adds another strategic consideration, which further ramps up the tensions.
