Guns, Blocks, and Steel

Guns, Blocks, and Steel is a FPS game with a completely dynamic environment. Build defenses, or, more importantly, destroy your enemy's defenses. Mold the terrain to your advantage with the Rocket Launcher.
Resources
Mine iron to refine and produce steel, which can be used to build vehicles and ammo. Ammo is limited, so be careful not to waste it. Some more advanced weapons of war may require gold, which is a more contentious resource than iron. Instead of boringly digging out each ore block one by one, like some other games, you must blow it up with dynamite. Or just throw the dynamite at the enemy. Whatever you want.
Play as you want
Your playstyle is your choice. You can stay behind at your base, manage your team's resources and construct weapons of war. Or you can try to gather resources and bring them back to your base. Or you can assault your enemy's base. Or you can do all three. There are no classes to railroad you into a certain role.
Fun over competition
Most multiplayer games nowadays try to get you addicted by making the game hyper-competitive, which fosters a toxic community. This is not what Guns, Blocks, and Steel does. The game aims to put fun over competition. Winning or losing doesn't matter as long as you had a good time. Your win/loss ratio is not tracked, there is no history of past games played, there are no rankings, and you cannot see the kills and deaths of other players.
