This is a great game. I have a lot of friends on it. But there are some glitches and i have an idea for the Gravity Gun. 1. My Idea For the Gravity Gun: The Gravity Gun has improved a lot since you added those 3 options. What if we could highlight things that are connected and pick up a whole house. 2. The Boss: The boss was too easy last update and now that the boss can heal by itself it has become almost impossible because you can't destroy the healers. 3. Saving Maps: We can't save maps.

This game is fun and all but the community is pretty bad. First of all, a lot of people don't speak the same language. Next, the hacker issue, I mean, they can one shot an apocalyptic car at full health, spawn 100 rpg rockets at once, cannot be kicked, etc. Finally, the issue with falling through the void, there should be a solid layer a small distance from the surface, or just fix falling through the surface in general. If these could all be fixed, that would be great.
