Description:
Cabin Fight is an Infection map based on a section of Resident Evil 4 where you are trapped in a cabin, and enemies continuously try to come in through the windows, both downstairs and upstairs.

Zombies initially spawn at the back of the two bases, but they can respawn just outside the cabin.

At the beginning of each round, the zombies will not be able to enter the cabin using the upstairs windows. There are 4 downstairs entrances, though all are blocked by crates. After several melee attacks, the crates are knocked aside, and the zombies are in to cause chaos.

45 seconds into each round, gravlifts spawn outside, allowing the zombies to enter the cabin upstairs. These windows are not blocked, so the zombies will be able to enter quickly. However, humans can destroy these gravlifts, meaning zombies will not be able to use them for another 45 seconds.

In both gametypes, humans start off with a magnum and shotgun with limited ammo. One extra shotgun will spawn downstairs in the cabin after 3 minutes, providing one lucky human (if there are any left) with much needed ammo.

2 magnums and another shotgun are available right from the start of each round, but they are found outside, putting you at risk of infection. Also, these 3 guns will never respawn, so if someone beats you to the extra ammo, you're out of luck.

Gametypes

In both gametypes, both zombies and humans have shields which do not recharge. Zombies are weak, and humans will take 2 hits to die. Killing a zombie is worth 1 point, infecting a player is worth 2. The last man standing earns 1 extra bonus point, and suicides/betrayals have a harsh penalty of minus 5.

Both gametypes are 3 rounds long, each of 5 minutes. Zombies are chosen randomly:

Las Plagas: 50% of players will start the round as zombies, using the energy sword as a weapon. They're weak, so they shouldn't be too much of a problem, right?
Dr. Salvador: 25% of the players will start the round as Dr. Salvador. He has more health than normal zombies (he takes 6 magnum headshots to kill, normal zombies only take 4) and he can kill you in just one direct hit with his gravity hammer. Anyone he infects will become just an ordinary zombie.
