is the VOS or Verbal Orders System. A list of substations along the bottom of the HUD correspond to number keys on the numpad. Pressing each number brings up a submenu for the corresponding subsystem, with possible additional submenus available for many commands. For example, pressing the numbers 1, 4, 1, 1 might bring the ship to full power and run weapons and shields at eighty percent, with a corresponding verbal acknowledgement from the crew. The other key interface feature is the Gunnery Chair. Simulating the periscope-like manual control system seen on Klingon Birds of Prey throughout the Star Trek feature films, this system changes the interface to allow direct control of weapons throughout all of the vessel's firing arcs. Flight control can be delegated to an AI helmsman or retained by the player, and the Gunnery Chair may stay locked onto a single enemy vessel or remain free to move through any firing arc. Ship systems, operation, and weapons There is an array of different weapons from the Star Trek series in the game. Players also have an array of systems and resources, including some such as marines which are concepts more familiar from the game Star Fleet Battles. Players can use tractor beams, and reroute power to various systems. As with most Star Trek games, each ship has shields divided into various areas of the ship. The player's HUD screen displays relative strength of each shield on other ships, enabling targeting of weaker shields. Interactive terrain Space is filled with various features, landmarks and terrain. This includes specific planets as well as other features such as nebulas. All of these affect gameplay. Klingon Academy is an open world video game. It is possible to warp to various points in the galaxy, such as planets, including Earth, and to view various landmarks there. Significance While being the same fundamental game type as its predecessor, Klingon Academy enhanced the formula in various ways to create a more complex simulation. Ship control, in particular, was dramatically altered with additions such as the "gunnery chair", multiple viewing angles, and a complex-yet-intuitive function key-based command system. Ship movement was generally slowed down to create a more tactical game by bringing forth the ponderous nature of Star Trek naval combat. This addressed one of the largest criticisms of Starfleet Academy; its fast-moving starships that were compared to a fast-paced fighter simulator. Klingon Academy is,
