About The Game
German censorship
Just like in the "Commando" (Elite Software)case, which has been rereleased in 1985 as "Space Invasion" (here's a brief comparision: Commando vs. Space Invasion), since Bridgehead was indicated in Germany, Kingsoft appeared again on the market with a "defused" version of the game, named "Alien Invasion", same code but differently compiled due to changes, slightly changed graphics.

Graphics changes
Apart of the obvious change in the title's graphics and the enemy sprites, all the levels show little changes or addons in the background graphics, in order to turn the overall atmosphere of the game into something more space themed. The year displayed in the levels scrolling demo remains unchanged, 1987.

Not for C16
A 16kB version has never been released, just has happened for Bridgehead C16: "Alien Invasion" runs on 32/64kB machines only.

Single release?
A hypothetical single release has never surfaced yet. Sextett's front cover reports little covers of the respective games' single releases, and to rapresent "Alien Invasion" there's a generic cover, actually no space themed by the way, which looks like a mockup indeed.

Level's counting bug
The entire level 7 originally from Bridgehead has been cutted down, but the level's limit hasn't been set to 7, so the game considers an eighth level too . Due to the obvious lack of graphics for it, the player must run in the garbage trying not to die, solve the level, then restart from level 1 as expected.
