A fixed-screen shooter where the enemy isn't a spawn pool, it's a hanging hive whose every cell holds up the ones beneath it.
Pilot a ship along the bottom of the screen and shoot up into a connected mass of alien cells. The hive is a structure: clear the cells underneath one and it loses its anchor, so smart shots can drop whole chunks at once. Survive the descent and dismantle the swarm before it reaches you.
A fixed-screen shooter in the lineage of Space Invaders and Galaxian, where the enemy occupies a structure rather than arriving from off-screen.
The structure here is a hanging hive, and every cell of it holds something. Shooting into it does not deplete a spawn pool; it opens the comb.
That changes what a shot means. In the ancestors, each hit removes one enemy and the formation shrinks predictably. Firing into a hive releases what was inside, so aggression is not straightforwardly good and the safest-looking target may be the worst one to open.
Hivefall is an original free browser game that reinvents the fixed-screen space-shooter genre by turning the enemy formation into a destructible structure with real load-bearing physics.
