This map is really good. It has two environments, a Citadel place which is linear and has a few Combine fights, and Cyberspace which is the highlight of the map. Cyberspace is where you have to take cubes to the end of the level. It’s not much of a puzzle but it’s easier said than done and is very fun to do. There’s obstacles and TONS of moving platforms and energy ball generator things. These parts are great. The map is obviously centered around the Grav Gun which you use to carry the cubes. You could just use your hands but it’s not as fun. The goal is to destroy a generator, which you have to go through the two Cyberspaces and a few Combine to do. This is a very creative and fun map to play, I recommend it.
