This series, more than anything else, really captures everything about the amiga for me.
Great graphics, the sense of playing "aliens the movie", sound effects, the haunting intro tune, the frantic two player action, the completely irreverent and obnoxious cheat codes. It was just perfect.
So lets talk about the series.
Which was your fave of the series?
Which ones have you beaten (no cheats or trainers)?
Fave weapons?
In short, talk everything Alien Breed 
Oh my.. really nice topic, like this one.
I played both AB, but i never had the chance to play AB3D. Never got the hardware to do so.
Number one and number two are by far my favorite Amiga game. And (believe it or not) i have never cheated in any AB game...
About favorite weapons.. anything that kills aliens...
