Thank you for downloading Vertigo 1.0. We hope you enjoy playing it as much as we enjoyed creating it!

1. Getting Started

Once you've unzipped Vertigo10.zip into your Half-Life folder, there are a couple of things that you need to do before you can jump into the action.

The first thing you need to do is copy some map files into the halflife\Vertigo\maps folder. Vertigo can access any maps created for regular Half-Life multiplay.

For example, you can copy crossfire.bsp and frenzy.bsp from X:\stuff\halflife\valve\maps\ to X:\stuff\halflife\Vertigo\maps\ (where X:\stuff\halflife is the folder you installed Half-Life to).

The second thing you need to do is bind a key to turn the jetpack on and off. Once you've activated Vertigo (through the Custom game screen) simply go to the controls configuration screen and map a key/button to the newly available Jet Pack entry.

That's it as far as setup goes. Start a multiplayer game as you normally would and enjoy the action!

2. Jetpack Control

Turning the jetpack on and off is simply a matter of hitting whatever key/button you just mapped to that action. While the jetpack is on you can control your altitude with the jump and crouch buttons (Jump to increase altitude and crouch to decrease it). You can also use the navigation keys as normal to move forwards, backwards, left and right.

The jetpack gets it's power using a battery that slowly recharges when not in use. Be sure to keep an eye on the jetpack icon in the HUD to make sure you don't run out of power at an inopportune time.

3. Modifications

The following is a list of the modifications that we've incorporated into Vertigo.

• Added the jetpack.
• Increased the number of rockets in the rocket launcher clip from 1 to 3. Decreased the number of extra rockets you can carry from 5 to 3.
• Added an extra (less zoomed) zoom level to the crossbow and decreased the time it takes to switch between zoom levels.
• Fall damage is now always based on a realistic model. We've removed the option to change the fall damage from the UI as this is an integral part of Vertigo.
