on the blood offtopic.
cryptic passage was super-neat, it had huge levels and great design, i wish they would have done another addon, it was great (except a few bugs with secret counts).
plasma pak was grim on the other hand, because apart from the new enemies and new firing modes, it recycled alot of levels from the floating-around blood alpha build of feb 96! check it out. that alone makes plasma worth it.
i always wondered why companies who almost abort their titles (fckng atari or whoeven owns blood right now after series of buying again and again?) don't like alphas or betas of games being, um... distributed. i don't see how it will harm the sales, especially in the blood case, which i think noone buys now. because the lack of support or something, fans are just forced to dig through the old stuff and find little and major differences - just because they don't have anything new on that game to toy with...
