Alien breed they are a classic, I never got alien breed 1 or 2, in fact the first game I got of the alien breed series was Tower Assault on the CD32, it was a great game, difficulty was set a bit too high however for me to ever to get too far into it, but still it definitely one of the best overhead shooter on the Amiga, not my favourite type of game play but it works in alien breed, and one of the better games that came out for the cd32.
I got Alien breed 3d very quickly after that and boy that game did rock, and made my friends believe that the amiga could do a doom game. But blasting them red alien dogs apart was great fun, got to the very last level but could not get past that big green monster at the end.
Alien breed 3d 2, technically brilliant and was the first game I tried out on my power tower amiga when I got it, (040-40mhz) but did any one play test this game, I got no further than I think level two or maybe three, it ridiculously hard, and I what I did play I have to say I found a little boring, I remember entering the room thats meant to be the bridge, but just looked like any other part of the level, from interesting levels designs AB3d1 did much better.
At the end of day I think I will regard them as classic but not awesome.
