Quake 2

You can skip the first level if you just jump over the bridge that gets exploded. For a fast way, watch from 3:55 to 4:03 in video 2, and in the re-cam video watch it from 12:22 to 12:34. They just rush across the bridge before it explodes [img]https://www.xboxachievements.com/images/misc/a.png[/img] (bunny hop), then rocket jump (fire a rocket down at the ground while jumping) [img]https://www.xboxachievements.com/images/misc/a.png[/img] away from the blast. The second way is to use a invulnerability power up so you can just cross the lava. You can also rocket jump, grenade jump,or barrel jump across, I recommend the first two, but the second one more as it's easier to do.

When you go complete fact2 and go back to fact1, look right, theres moving pillars with lazer, go across this area. (see 5:07-5:15 on second you tube video) (13:41-13:44 on re-cam) then you're done with this level set.
