This is a simple and effective strategy where the players are camped in the narrow alleyway of the bus depot. Many of the special infected get stuck behind the concrete wall (at the far back) over time. To get a better flow of zombies, they should be shot through the wall.

Supplies
Any weapon can be used, however, it's recommended to use sniper rifles, whose penetrating shots are very useful in the alley. The sniper rifle is also excellent for ammo conservation. Pistols or melee weapons can be used, depending on the player's preference of sidearm for the ammo runs. All supplies are moved to the alley. Gascans can be stored above ontop a ledge.

Positions

• One player concentrating on the front (A)
• One player concentrating on the back (D)
• Two players serving as backup, in the middle (B \& C)

Notes

• The faster that the team can kill tanks, the easier this strategy becomes.
• Three players focus on the tanks while one person clears out the opposite way so that the survivors have room to back up.
• Tanks may come from the side and climb over the fence into the alley. These tanks need to be dealt with swiftly.
• In the case of double tanks sandwiching the players, the players need to focus on the closest tank and kill it first.
• The ammo runs after twelve minutes should be done when there is a lull in the tanks. If a tank has spawned very far away, ammo can be retrieved provided that the ammo runs are done quickly.
• The players should keep cover behind the green fencing instead of the mesh fencing as this will block smokers.
• The front player should not be positioned too closely to the entrance of the alley as chargers will charge down the alley immediately.

This is the most effective strategy, however, it requires very high skill level with sniper rifles to pull off.

Supplies

All players use sniper rifles, which are reloaded through the sniper spawn at the tower. The player at the fence walks across the fence onto the tarp to retrieve ammo. Supplies are moved either on the tarps or on the scaffolding (it's difficult but possible to move the items to these locations).

Positions

• 2 players at the tower (A \& B)
• 1 player on the scaffolding near the front (C)
• 1 player on the fence (D)

All players use sniper rifles. Items were moved for easy accessibility.

• Good communication is essential for this strategy because during double tanks, the focus of the players are split between the two tanks.
• The two players at the tower can deal with back tanks with very little help.
• The player at the fence has to deal with the front tanks and specials coming from the front. He can lead the tank in circles by making small movements along the fence.
• The player at the scaffolding serves to backup the side that needs help.
• A lot of the fire can be used in the first 30 minutes. After that time, the special infected will get unavoidably stuck and the pace of the map will slow down.
• All players use the sniper spawn to replenish their ammo.
• It seems that the faster the tanks die, the easier this strategy has become. This requires a lot of shooting.
• For the front player, he is playing on the fence to bait the tanks but retreating to the tarp to avoid rocks.
• The back players are spamming the sniper rifle and they alone should be able to kill all back tanks and even double tanks at back.
• According to statistics, the back players are doing the brunt of the damage to the tanks.
• We improved on the amount of times falling off the fence and scaffolding. We used throwables whenever someone fell in order to recover.
• The fence player moved to the tarp, where he was healed by the players on the tower. The fence player required the most medkits (that was me :P)
• When it is clear, the fence player is clearing the front scaffolding of zombies and especially chargers climbing the scaffolding.
• Special infected will sometimes move from the back through the alley to the front. In this case, the back players gave warning.
• The roof tanks were getting killed by mostly the back players with help from the front scaffolding player.

The weakness of the strategy is that when players fall off the fence or scaffolding, it can be difficult to recover. We had little problems with this until the end, where we wiped out at 55 minutes despite having about 3 medkits and 1 defibrillator left. An hour is definitely possible with this strategy, which phoenix actually predicted, yet nobody believed him!
