Yeah, this is the one I suddenly recalled in terror soon after we started on this series. An epic level that I would really rather not have to go through again - seeing it written down here just emphasises the length! I would also mention that in the many trips back to the 2x recharger in the lungs during much of the level, I always tend to get most frustrated by the alien-like objects lining the corridors - especially when navigating on map view!
That last puzzle bit is quite something as well - as I recall there is a bunch of pirates to fight on the side of the platform as well, and this sometimes gets a few bobs coming out to help, which can just increase your chances of getting 'assimilated'. And then the platform, I remember the run forward, run back to get on it in time, and that only worked some of the time - then the other side can be touch and go as well, and if you need to come back out from the last offensive to recharge you have to go through it again.
Can't remember which the next level is but I'll play this one this evening and then find out. I have my suspicions....
