It is visually exciting, with many special effects, including fades, scaling and rotation. Game control is solid with additional options for those who need them. Patriots code is optimized to make the game run very, very smooth. Vectrex "flicker" is almost nonexistent, except for higher levels with tons of missiles, patriots and explosions all happening at once." Supports trackball input.
