Blood Money is a game by DMA Design (the creators of 'Lemmings'). It's the sequel to the awfully bad 'Menace'.
a more in-depth look at the game I advise you to read my review
of the Amiga original, as this review will concentrate on the differences
between the 16-bit versions and this 8-bit port. However, I'll give
you a quick overview: You control various crafts through four huge
levels. Shooting enemies earns you money that you can spend in shops
on powerups. That's about it. The extras aren't very special, but
the level design holds some surprises.
The most astonishing diference to the Amiga original: The game is much better on C64. The hit detection is a lot friendlier this time. Additionally, the levels have been shortened, so it's actually possible to beat them. Most unfair scenes have been removed, too. This especially applies to level four. New are some scenes in which you have to maneuvre very carefully through tight passages. Oh yes, and you can't select the order in which you want to play the levels anymore. You'll have to tackle them from easiest to hardest (which probably is the best order anyway). However, the great 2P simultaneous mode is still there.
The graphics are ported nicely. Only some of the bigger objects got a bit pixelated. This is probably due to memory limitations.
Sfx and music are good. But the latter lacks the extraordinary melancholic quality of the 16-bit counterpart. And, yes it's still only one tune you hear throughout the game. And it's still impossible to have music and sfx at the same time.
Overall, apart from being not very original, Blood Money for C64 is a very entertaining and highly underrated game. I can recommend it to everyone who doesn't particularly dislike 8-bit shmups. Avoid the frustrating 16-bit versions, though!
