Its said you cant really throw one ahead in hallway, as it bounces around 4 or 5 times then comes right back at you, lol.[/]
The grenades have to be timed to explode on impact. You have to listen to the whine and judge when to throw, makes it more likely that you'll get your hand blown off but makes it more skilled than blowing up all the waiting creatures and then saying 'well that's easy' or summat.
My biggest problem with this game is no MAP! Even a basic chart. You got this excellent video enabled PDA but half the time I just wander around until something opens or theres a bit I haven't seen yet. It would make the storyline more coherent than random messages. Still thats about it on the real downsides. Not sure about the physics stuff cos I haven't been to a hell infested Mars lately:D The flashlight swapping is fun but whatever floats yur boat.
Top game, could have been the shambles that was Unreal2, instead is more a half-life/system shock/doom cross, which is bobbins. Off to try that unpacking thing now to see if it speeds up or blows up...
