This is a project I worked on many years ago. As far as I know, it was never finished but I like the grid. The player controls a small ship moving across a grid made by aliens in Earth orbit. The player must shoot the aliens and spawnpoints. The final goal is to destroy all the bosses - special large structures attached to the grid.
The grid is a mixture of 3D elements and hand painted elements; the ship and aliens are completely 3D. Many elements are animated.
A piece of grid with some bosses and spawns.
Ships and aliens - sprite atlas.
Damaged alien spawnpoint. - damaged versions.
