Grid Assault is a faithful clone of Geometry Wars: Retro Evolved from the Xbox360.

Keys:
1. Cursor keys or gamepad to navigate menus
2. Press P for pause
3. Press Z to take a screenshot
4. press ESC during play to return to title screen
5. press ESC on titlescreen to exit game

Current "features":
1. When you reach level 20, it's game over! How much can you score before that time?!?!
2. BlitzMax sound system sometimes craps out, stopping looped sounds or not stopping
3. them at all... This sux, but I keep working at it.
4. The EMS 'Dual Shooter' PC USB -> PlayStation/2 adapter has two inputs. Although it supports 2x [daisy-chained] lightguns or 2x individual joypads, each port on the device is labelled; the primary one is marked "game controller" and the secondary, "gun controller" leading the user to possibly assume that these are the default ports for use of only one controller of either type. In '360' any joypad needs to be connected to the secondary [as confirmed in Windows' settings] / "gun controller" port, rather than the primary / "game controller" port (as one would expect) for it to be recognised by the game.
