Although you can rely solely on your keyboard to move around
in and interact with Unreal's 3-D universe, using both the keyboard
and mouse simultaneously gives you much more fluid and
responsive control.
When you use the mouse to control your rotational movement and
aiming, you gain a degree of precision and speed that players using
keyboard-only controls can't touch. The keyboard is best used for
Note: Some of the doors and lifts in the game are automatically
activated when they detect your motion or body heat as you
approach them. If you have trouble activating one of these
sensor-controlled devices, move back to reset the sensor and
approach the door or lift again.
Pushing Things
To push objects, buttons, switches and levers, run straight into
the object you want to interact with. If the object can be moved
or interacted with, this will take place automatically.
Shooting
To use your weapon’s Primary Fire function, tap the Ctrl key
or the left mouse button. For Secondary Fire, tap the Alt key
or right mouse button. For continuous fire, and other enhanced
firing functions, keep the fire key depressed. See Weapons for
detailed descriptions of each weapon’s Primary and Secondary
Fire functions.
Jumping
To jump, tap the Space bar. If you jump while running, you
will jump farther and in whatever direction you are moving.
Strafing
Learning how to strafe effectively to dodge the enemy is a vital
survival skill.
Swimming
When in deep water, use the movement keys to swim just as
you would to run. Look down and move forward to swim down,
and look up and move forward to swim toward the water’s surface.
Unless you are wearing Scuba Gear, you need to make sure
you come up for air from time to time or you will drown. Hold
down your jump key to tread water.
