A 2-part mission, starting with a train level and then the namesake.
The thing about multi-map missions is that your buffs don't carry over, you have it for one map and that's it. Same goes for any budget you earn and lose based on your set equipment, it's a payout per map, not for the entire mission, so if you check your earnings, it will mostly show a small number, which was the last map you've beaten.
The second part is also something that before 4.5 was heavily prone to softlocking due to Zaxtor's strange scripting, as the valves in the original version are infinite switches and you cannot save once you start to do that to overload the reactor + it breaks some of the scripted stuff at the end.
This was changed for 4.5.1 and now there are actual switches next to the valves. Before I even decided to record these, I had to re-do the second part like 5 times on my first go-around in 4.5, due to the switches either being in the floor or some script breaking.
