From ThinkGeek:
For those of you that loved the original Khet, you're gonna just flip
for Khet 2.0, but we'll sum up game
play for you who are new to the game.
In Khet 2.0 Laser Game, there are four
types of playing pieces, and two of
them have mirrors. Game play is
simple, and easy to learn, as there
are only a few movement choices. The
goal is to eliminate your opponent's
Pharaoh. And, you eliminate the
Pharaoh just like they did in olden
times - by firing a red laser! And
this is where Khet 2.0 kicks the game
up a notch.
In the original Khet, the lasers were
part of the board. But in Khet 2.0,
the lasers are built in to special
Sphinx pieces that perch in the corner
and can now rotate to change the angle
of the beam (because of this change,
the board is very slim and now built
to travel)! Your laser is fired after
your turn and bounces from mirrored
piece to mirrored piece (always
shooting off at a 90 degree angle). If
the laser hits any piece on a
non-reflective surface (with one
exception we'll leave as a surprise),
that piece is removed from play. If
you eliminate your opponent's Pharaoh,
you win. If you eliminate your own
Pharaoh, you will be mocked for all
time (because it is possible). Khet
2.0 Laser Game is the next generation of the best laser game of all time.
So it seems that the form factor has changed, the lasers can be rotated, and there's a new piece added.
