Tetrinet 2 is already in
beta, this version doesn't include
server files, And is only for
Windows.
But it's really fun. It has tons of
improvements over the older versions.
You can get it in here http://boards.gamers.com/messages/overview.asp?name=tetrinet (also the official
forum of Tetrinet 2)
There are a lot of new
features, but the most notable are the new
blocks:
(Shamelessly ripped from the Tetrinet 2
readme)
- Clear Column - Clears a line vertically
- Attack Immunity - Invincible to attacks by you or your opponents
- Darkness - Blackens your field for a period of time, but leaves a bubble of light so you can see a limited area around the falling piece
- Confusion - Rearranges your controls for a period of time.
- Mutated Pieces - Gives you several difficult-to-place pieces that are randomly generated.
