First you will need a gun other than the pistol, head west and then turn south, the westen door will open and a red alien will run out, kill it with the pistol and you will rank up (you will need the extra health). Then run in to the way it came and instantly turn south through another door to find the rail gun. At this point you'll be being piled by a large amount of red aliens which you should instally kill with the rail gun, ou will rank up at this point as hence be fully healed. Head back out the the corridoor and head, not in to the one direclly opposit you, but the door further south on the east side, on head through the door on the other side of this room to collect the autogun.
Afterwards, grab 3 out of the 4 available explosive charges. (You only need to collect all 4 if you are going to try and get Gordon's Alive! on level 10.) It is recommended to plant the first bomb at the southern site. The second bomb should be planted at the eastern site. After the last bomb is planted at the western site, a lot of monsters will spawn, so prepare to use the rail gun. Then run to the exit.
