The Story so Far...
A new airborne virus has started spreading across the planet. While many people have been killed by the virus, a great chunk have been turned crazy. Not even human anymore. Feasting on the flesh of the living, the few people who have a natural airborne immunity to the virus find themselves completely outnumbered. In the populated city of San Oatlos, a small group of survivors have escaped the infected by venturing to the depths of the sewers. While safe at the moment, they know that staying with limited weapons and no food or water would be a death sentence. One of the survivors claim that there is a military outpost on the other side of the city. Though many of the survivors are doubtful, this might be the only choice and staying to rot in the sewers was not an option. A risky plan but doable in theory? Yes. Actually putting the plan into action? Not so much.

The Survivors

Though stronger than the regular infected, it won't take too many hits before you're down. Remember that you don't have a radar and can still be assassinated so stay together, watch your backs and keep health packs handy.

The Infected
Regular Infected

Generally weak alone, it won't take too much to take these ones out. What these guys don't have in strength however they have in stealth and agility. Fast and always aware of your location, when they start charging en masse start praying.

Tank

Mutated by the virus, these things can dish out just as much damage as they can take. Remember to combine fire on this infected or you'll find yourself as one of them pretty quick.

How many players?
Although the map is normally set to 4 infected at start, this is meant for a party of 10-16. If your party is not of that size, don't hesitate to lower the number of infected zombies to your preference.

Objectives
Survivors
The goal for this is not to camp and get as many kills as possible. While there is a scoring system, the No Hope campaign is meant to be played as a linear level much like you would see in Left4Dead. The objective for the humans is to get from the begging of the level to the saferoom at the end. The following the guide to get to the end as the humans.

You will start off in the sewers. Walk out and turn right down the alley heading towards the diner- the first holdout area. You're very limited with weapons so keep sharp and watch out for zombies from above, below and in those little spots you never think to look.

You've reached the diner. Hold out until 2:00 for the door to open. It'll be easy at first but over time, you'll be finding yourself spraying you rifle for life.

The door has opened. Enter the diner, pick up whatever you need and get out through the back door fast. Make your way to the office building.

You've made it to the office building. Climb up the ladder and get inside using the stairs as quick as possible.

Hold out in the saferoom until 20 seconds remaining. A trip mine will spawn and you must use it to close the safe room door. If you've managed to do this, congratulations. You have finished Act 1.

Infected
Your objective is simple- kill the humans. To aid you is a teleporter system used to getting around the map quickly. As the humans progress through the map, some teleporters will close and new ones will spawn. Ramps will also spawn to aid you in getting to the survivors easily.

Strategies
Humans

Stay together, there is safety in numbers. Do not go ahead of everyone else and do not linger. Both will only lead to death.
Keep your backs against the walls. You can still be assassinated and you don't have radar. Cover each others backs.
Combine fire against the tank.
Always check corners and watch for the rooftops. Be quick but stay alert.

Infected

Use the rooftops and objects as cover. Humans do not have radar so go for the assassination.
Charge together. This makes it harder for the humans to kill you, charging in alone will lead to nothing.
When you get the tank, charge in with other people or use them as distraction. Going in alone will only lead to death from combined fire.

Comments
I hope you guys enjoy this Act 1 remake, I tried to keep it as true to the original while still vastly improving it. If you want to see the original Halo 3 version click here. The warthog was taken out due to confusion and the simple fact that it was too stinkin' hard. The holdout in the Halo 3 version at the end is replaced by a safe room switch. Thanks to everyone who helped test this and give all the suggestions to help improve Act 1: The Sewers. Keep an eye out for Act 3 :)
