reactors have not been destroyed and the teleporters are discovered. Players cannot save the game in a secret level, and have to teleport back to a regular level in order to save their game progress. The player's ship is protected by a shield which decreases when incurring damage from attacks and collisions with force fields, is replenished by picking up shield power-ups, and like energy is limited by a capacity of 200 units. If the shield is fully depleted and the ship takes any additional damage, the ship will explode, costing the player one life and killing any hostages on board, leaving most of its weapons where it was destroyed. A respawning player has to start at the level entrance with a ship having only minimum armaments, so it is often challenging to retrieve their previous ship's weapons. New to Descent II is the ability to drop weapons, so a player can stockpile surplus weaponry in safe locations in the event of a respawn. Failing to escape the mine during the self-destruct sequence will also cost the player a life, as well as their power-ups, and any hostages embarked, although having destroyed the reactor or boss robot the player will still advance to the next level. If the player loses all lives, the game will end, and their high scores are recorded. Points are gained for destroying robots, rescuing the hostages, and end-of-level bonuses based on the player's performance with score multipliers for escaping the mine; scoring enough points results in an extra life. Descent II also features a multiplayer mode whereby two to eight players can compete against each other in several game types, which include a deathmatch mode called Anarchy and Capture-the-Flag, in which two teams compete against each other to capture opposing flags. Conditions for ending the level such as maximum time limit, how long the reactor will remain invulnerable before it can be destroyed, and the number of kills to reach can be set, as can which power-ups to allow and whether players may drop surveillance cameras. The game also features a co-operative mode that allows up to four players to work together to complete single-player levels. A player can send messages and predefined taunts, handicap their ship's shields they begin with after respawning, and in Capture-the-Flag drop and pass flags to their teammates. Descent IIs multiplayer was designed for modems, null-modems, and local area networks,
