Green Things

Program 5K, graphics 2K. Author Clive Feather

You are cruising in the exploration ship Znutar when suddenly your computer informs you that green things have invaded your ship. Your only hope of survival is to destroy the green things, but since the alien life-form is unfamiliar to you, you must discover the effect of each weapon.

Ship Plan

The ship contains a number of rooms linked by corridors, each of which is identified by a number. A plan of the ship can be obtained, with your current position shown inverted, by typing RETURN to the prompt:

MOVE?

Replies

The reply to most questions is either Y for yes, N for no, or the number of a room or corridor in the ship.

Attack

You can either attack the green things hand-to-hand or using a weapon. The weapons are scattered around the ship, and you may carry up to two at a time. If you attempt to pick up a third weapon, the message:

DROP WHICH (0/1/2)?

will be printed. A reply of 0 will leave you with the weapons you are already holding to take the one you tried to pick up.

Note that fuel cans and gas bombs must be thrown through an explosion-proof door into another room.

Hints

1. There is more than one of each weapon.
2. If left alone, the green things will grow, lay eggs and move around.
3. You will only notice weapons when you stop moving
4. You can be killed if you encounter a large number of green things

Good luck - you will need it!

Ballistics

Program 3K, graphics 6K. Author Chris Cant

A two-player game in which you take turns in firing shells at the other player. The problem is made more difficult because in each game you have to take into account the direction and velocity of the wind, and the shape of the hill. If you score a direct hit, the gun will explode.

Turns

In his turn each player enters the velocity of his shell, followed by RETURN, and then the initial angle of the shell, followed by RETURN. Each number should be an integer, and DELETE can be used to erase incorrect entries. The numbers for the last two attempts are displayed on that player's side of the screen.

Snake

You are in control of a snake which you can guide around on the screen. The aim is to grow the snake by guiding it towards digits which appear on the screen; if it eats the digit, its length will increase by the value of the digit.

Game Controls

Z - Left, X - Right, [ - Up, / - Down

If the snake collides with the walls, or itself, you lose; press any key to start again.
