Level 07 is a very hard level.
Here a short navigating guide (the blue number is the room-number):
67: shoot elevator on while free fall. go right so take Powerup.
50: duck until canon shoots.
The main layer should be played in several stages:
Stage A Go like shown in map above, and consider:
19: go right in room 20 to save.
25: shoot elevator on (blocks enemies)
33: shoot down Powerup
36: wait until civilians have gathered in front of the gate
37: wait again for civilians, the go (Losses, however, are difficult to avoid). Leave room when the gun has killed the pirates
38: fire at hatch to open it
29: kill all hier alle haunter, elevator ON, go up
19: enter the passage backwards, running in the back layer to room 72 and wait until civilians leaved the sector. Back to room 19
Stage B Go like shown in map above, and consider:
13: go right to room 14, and destroy glass capsule
12+11: Warning: nasty, deadly trap hatches (indicated by small beige dashes)
10: up and take the pump-gun - save one shoot!
16: fire on hatch to open it
10: kill all haunters
As before: escort the civilians to the sector exit in R72
Stage C Go like shown in map above, and consider:
22: elevator OFF to free the both civilians.
Stage D Go like shown in map above, and consider:
21: let the civilians wait (show with weapon on the ground until a white cross appears)
22: elevator ON
15: very common case: kill enemy with shotgun before he can disable the elevator (when you get in the elevator align weapon)
