Introduction --------------- Invaders is a PC shareware version of the classic arcade game. You know the idea: swarms of aliens are attacking Earth and you must defend it using your limited supply of space attack ships. The seminal coin-op of yesteryear has been reproduced with every detail intact - crumbly shields overhead, sleek flying saucers scanning the land below, lasers whizzing about at high speed. Read on... --------------- 2. Requirements --------------- In order to run Invaders, you need: 100% compatible 386 PC or better MS-DOS 3.3 (or equivalent) or higher VGA/MCGA graphics card or better Approximately 115 kbytes (0.115 Mbytes) of free disk space A Soundblaster, Adlib or compatible sound card is recommended Invaders can be run from Windows but it is recommended that you close as many programs - particularly any games - as possible before doing so. Invaders will probably not run at optimum speed (or may not run properly at all) if run at the same time as other games. To achieve maximum animation quality when running Invaders from Windows, use full screen mode. Pressing Alt and Enter toggles between full screen and partial screen mode. At least one make of sound card is not 100% compatible with Invaders sound. If you experience lack of sound, make sure the sound driver program is all set up and the speakers are plugged in. Check that other programs bring the noise. If running Invaders under Windows, try opening Volume Control at the same time as Invaders. Fiddling with the MIDI balance control may cause the sound to work. ---------- 3. Playing ---------- Protect the Earth from the alien invaders by firing lasers at them all before they land. You have three ships at your disposal, each of which has an unlimited supply of lasers. Only one laser can be fired at a time. If one of your ships is hit by an alien laser, it is destroyed. A new ship flashes to indicate temporary invincibility from alien lasers. Green shields provide limited protection from the alien lasers. You fail if the aliens land, touch you or destroy all of your ships. Different alien breeds give different points when shot. Shoot the blue flying saucers at high altitudes for 50 bonus points. An extra ship is awarded when your score reaches 5000, 10000, 15000 and so on. If you have a high score when your game is over, you will be asked to join the Invaders Hall Of Fame. Type your name in the box when it appears. You can use the up cursor key and down cursor key to recall previous names if you don't want to type your name again. To reset the table and go back to the default Invaders table, delete the HISCORES.DAT file. You could do this to spite someone else who has a higher score than you, but that wouldn't be a very sporting thing to do. ----------- 4. Controls ----------- Your ship is controlled with the keyboard. Pick your favourite combination of keys from the choices below: MOVE LEFT MOVE RIGHT FIRE LASER left cursor key right cursor key up cursor key q w Alt o p Ctrl z x Space Any combination of the above can be used. Most people seem to prefer the left, right and up cursor keys. Also: Pause/Break to pause and unpause the game Esc to quit the game. --------------- 5.
