Level 1: Lunar Outpost
Enemies: Class 1 Drone, Class 2 Drone, Small Hulk
This level is fairly easy to start you off. There’s a Red Door to the left and two passages straight ahead and below. The passage to the left leads to Class 1 and Class 2 Drones while the passage to the right leads to the Hostages, Red Access Key and an Energy Center where you can replenish your lasers.
The Red Access Key is in a room protected by Small Hulks and Class 2 Drones. Take them out, grab the key and then make your way back to the Red Door at the beginning of the level.
Reactor Core: There’s a few Class 1 Drones and 2 Small Hulks protecting the reactor core. Keep moving and take out the robots. Keep shooting at the reactor core until it explodes and you’re given a timer to get out of there.
Exit: Ground level on the opposite side of the room from the reactor core.
