This level introduces the logikill. It's basically an ice spindle robot with plasma core.
This level contains a portal to the secret level 2.
The beginning of this level is very hard. Don't use your missiles because it lures all the mechs in once making it really hard to deal with them, with a level 1 laser. Pick them off with laser only by peeking out at the corners. If you are lucky the logikills drop a helix cannon, so your firepower improves a lot.
The matcens at the ceiling of the shaft can be triggered many times by going next to the exit, and both of them activates when you pass that little doorway that leads to the first lavafall.
Once you manage to clear and get behind the first lavafall the level becomes a bit less problematic, because you can collect all the good stuff from the secret level. Mostly smart and guided missiles. I didn't use them till the red door.
If I hadn't picked up the shield sphere near the matcen at the end too early, I would have exit this on 200HP...
