This is my UNSC Razorback, accompanied by the ship Jacob's Brick. Each ship has 2 floors and a hangar, as well as multiple chokepoints and defensible areas. Best played 8vs8 but can be played as low as 4vs4. It is made in the sky bubble, and you start with lasers and ARs. To be played with the associated gametype.

Gameplay usually breaks up into 3 stages.
Stage 1: Lasers firing back and forth between the ships, one is bigger but the other has more portholes to fire through.
Stage 2: Either hornet/hornet combat or laser/hornet combat while attempting to board.
Stage 3: In-ship combat.

Yes some of the walls are sloppy :( sorry about that, but it doesn't affect the gameplay.
