I had actually never beaten this level before, so I decided to try it for real and cranked it up to TC. After 2 or 3 tries, I was doing pretty well, having cleared most of the second layer down (large arenas with 2 juggernauts each) and secured the "home bases" at the end of the spokes, and was just starting on the multilevel core when the game FROZE. This did not exactly inspire endless perseverance, so I cranked it down to Normal and beat the level pretty quickly.
There are additional items present at the start for co-op players (more 3x chargers and guns), but the level is not marked for co-op play and thus will not appear in the gather network game dialog unless the secret cmd-opt-gather trick is used (which allows you to start a co-op game on any level of the current map file).
: Although this is an extermination level, since the
: monsters teleport in, you can elect to explore only one spoke, but you may
: miss out on collecting fusion ammo if you do so.
The level is described as an extermination mission, but the actual mission flag isn't used and you don't have to kill all the monsters to leave.
: Fortunately, he will not leave the center region, although he'll move
: around to try to get a better shot at you, but you can always dodge him by
: hiding behind walls. Once he's gone, simply log into the terminal to be
: taken to the final screen. Seems this was not virus at all, but a
: neurotoxin injected by a cybernetic flea. Pretty lame again if you ask me.
Of course, it's possible to blast him out of the center yourself, especially if you're throwing nukes.
