Original C64 manual
Encounter is a fast-action game in three dimensions. Your view is through the forward command window of a probe vehicle. Your instrument panel combines a radar scanner and warning lights.
You are exploring a vast plain littered with mysterious cylindrical obelisks. Your incursion has triggered a relentless attack of alien saucers and homing missiles. You can move freely over the battlefield, provided you avoid the cylinders, and can fire at will. Shots fired by the saucers, and your own shots, will rebound from the cylinders.
Beware, you can be shot from any angle, including from behind. The homing missiles, which are not stopped by the obelisks, are particularly dangerous.
The game can be progressed through eight levels. Each level displays a different landscape and presents you with new enemy strategies. On eliminating all of the enemies at one level, take a 'stargate' to the next level. There is an audible warning. The position of the gate is indicated on your scanner, as a blip. Head towards this quickly, and you will see a black rectangular hole. Line up with the center of this gate and then proceed through.
You will be propelled at high speed through a hail of spheres, which you must avoid hitting, to attain the next level. When the gate appears, an extra shield is awarded (subject to a maximum of nine). If you fail to pass through the gate in time, or fail to negotiate the spheres, you are returned to the previous level and lose one shield. You may re-start at any level that you have completed in the play session, by pressing a number key corresponding to the level required. A buzzing sound acknowledges that this level is accessible to you. Then press the F1 (START) key to begin play at the level selected.

You are warned of a saucer's presence by a yellow indicator on the instrument panel. A trace on the radar screen identifies the position of the saucer relative to you at the center. A blue light will flash when the saucer fires a shot. Its target is your position. Move at an angle towards or away from the saucer to avoid being hit. You are warned of the approach of a homing missile by a flashing red light and the sound of its low menacing whine, which increases in pitch as it approaches. Its position is shown on your radar screen. Turn towards the missile and back away to gain time, but be wary of hitting cylinders behind you. You must shoot the missile, or it will hit you. Just don't stand still!
