xen-jumping????
 

Just arrived to xen. Where do I jump? Can´t make any long jumps, have I missed to pick something up to help me jump longer??
Thought I heared a scientist say something about a "longjumping suit"??????????
I´m a dedicated HL-fan from Sweden.

Listen, you will not be able to complete Xen without the long-jump pack. So, if you have a game saved before you went into the alien world, go back there and pick up the long-jump module by the scientist.

Now, once you have the jump-pack and get to the planet, look forward to the small island. Now, run forward, then duck and jump. You should literally fly onto the island. But before long jumping again, wait a moment so your jump-pack can recharge. Go to www.halflife.net for a good walkthrough.

Why have I (In some multiplayer games) been able to jump very high in the air and very far. I have been able to jump to third story roofs! Can somebody explain this?

You were on a low gravity map...
Or whoever set up the server made it low gravity...
