Grineer Galleons are the second tile set for Grineer after the Grineer Asteroid Base. The Grineer Galleon has a rather dated atmosphere, with grimy hallways and large docking bays to hold and maintain smaller vessels. Dark and foreboding in most areas, the Galleon is mostly lit by the light of the stars shining through the windows.
- If an Infested mission takes place on board a Grineer Galleon, the tileset will feature large masses of Infested biomass, sometimes altering the paths available.
- Interestingly, while the Corpus Ship's navigation console displays a hologram of its exterior, the Grineer Galleon's navigation console depicts a spiked sphere that is notably similar in appearance to the mines being dispensed in one of the possible tiles.
- Two small Grineer spacecraft can be found suspended in the Hangar tile, similar to those flying by in the Grineer Forest extraction tile, as well as in the Grineer Asteroid Base Hangar tile.
Certain areas of the map, one of the big gun rooms for instance, causes enemies to stretch out or die in mid air frequently, causing frame rate problems or crashes.
