Basics
Press the Fire Air Weapon key to release weapons that will deal with airborne enemies. This key can be held down to power-up the weapon, emitting a stream of destruction on release. Be careful not to overload it though!

Additional air-to-air weapons become available throughout your mission. To cycle through these weapons, press the Select Air Weapon key. To succeed in your mission you will need to master the art of changing weapons quickly and selecting the appropriate weapon for the target.

Pressing the Fire Ground Weapon key will launch Plasma Bombs. These are used against ground-based installations and mobile enemies. The crosshair will glow red whenever it is over an enemy. This weapon automatically increases in power as you progress in your mission.

Default Controls:

Using Gamepads and Joysticks with MacOS 8/9
When running in MacOS 8/9, Apple's InputSprocket is used to configure both your key settings and InputSprocket compatible game controllers. To configure a gamepad or joystick for use with Deimos, plug the device in to your computer, then go to the Preferences option at the Deimos Rising main menu and press Set Controls...

Using Gamepads and Joysticks with Mac OS X
If you are running Mac OS X, you can configure your key settings and your gamepad settings separately. To set keyboard commands, go to the Preferences option at the Deimos Rising main menu and press Set Controls... To configure a gamepad or joystick, plug the device into your computer, open the Preferences window and press Set Gamepad Controls...

If you are using an analog controller, Deimos will need to calibrate each axis before the VacFighter will respond properly. This only needs to be done once, after which Deimos will remember the calibration. To do this, just follow the instructions at the Gamepad Controls configuration window.

Using Keys
When playing via the keyboard be aware that there are limitations to the number of key presses that your machine can recognise at any one time. We recommend that you assign some controls to modifier keys such as Command or Option. A light tapping action works well.

If you experience any unexpected loss of inputs, try disconnecting any non-essential USB devices and start Deimos again.
