In the original Space Invaders was it the bottom-most alien in each column that fired at you or did the whole armada fire?

There are a tonne of clones out there...

I found a good clone of the original and it looks like only the bottom-most alien fires.

HTML5 canvas Space Invaders clone - non playable.

Thanks.

On the playstation 2 Taito Legends compilation it features the original Space Invaders as a direct conversion/emulation from the arcade machine. All the aliens are capable of firing and do so.
Also when you have less aliens left after shooting down a few, the remaining ones will each fire a lot more frequently.

So the aliens in the higher rows actually fire through the aliens beneath them?

I've seen that in a lot of clones but always attributed it to programmer laziness.

I personally think it looks much better if only the bottommost alien in each column fires.

It's definitely only the lowest alien in each column that fires in the original version.

Here's a flash emulation and here's a JScript/HTML5 version [edit]Which you've already seen, it appears?[/edit]

This site suggests things are a little more complex:
Any missiles dropped by an invader on the row above 'invasion' row will not harm the player's laser. This is a very important feature and one that must be fully exploited in order to obtain a high score. This will be dealt with in detail later.


There's a set of tutorials for writing an emulator in BlitzMax using the original ROMs knocking around so, y'know... :)

EDIT:
It's definitely only the lowest alien in each column that fires in the original version.
Yeah, looking at the emu you linked, defo -- I think the weird stuff on the page I linked is specifically about the "Wall Of Death".
