yes there is to be... and it'll again not be made by Epic (though its not been officially announced yet, story will pick up from where Unreal2 leaves it)
and yes if you complete on hard there is something VERY worth while that gets unlocked - but if you wait a month or two i'm sure someone will make a hack patch for it
the game does really need a REALLY powerful graphics card to look truely awesome
i have to get it, cause i wanna know what actually made it in - cause at one point they had Raytrace Refleactions ... i mean it wasn't like CGR style Raytracing but it still made certain sections look bloody amazing, like the Groyga Gorge - look down into the fog and see the water sparkling, looks outstanding ... even more so if you jump off cause right before you die you see your reflection hehee
there were so many funny tech demo parts to this game i had fun finding them all out - like turning off the gravity and moving with the machinegun ... no point in it, but fun
Tsu'va Oni Ni Jyuuko Fiori Sei Tau!
One block follows the suit ... the whole suit of blocks is the path ... what have you found?
