Line of Defense download for PC is an MMOFPS that takes place in an extended science-fiction universe created and maintained by 3000AD. All other titles of this independent studio (Battlecruiser and Universal Combat) take place in the same futuristic world and focus on large-scale warfare.
The action of the game takes place on Lyrius, a planet housing a number of research centers dedicated to military technology and biological studies. Unfortunately, after a few decades, the natural resources of the planet have been depleted, constricting further progress into many fruitful projects. The owner of the laboratories, a powerful space empire known as GALCOM, has decided to abandon the research sites and focus its attention to other projects. This move was used as an opportunity for Terra, a rebel faction that attempts to overthrow the empire. The rebel forces have taken control over the bases on Lyrius, and murdered everyone who put up any resistance. Thanks to a newly acquired site, Terra is able to finally stand up against the empire.
Line of Defense download is a MMOFPS which enables us to take part in massive multiplayer battles between two factions: GALCOM, a major space empire, and Terra, the rebels fighting to overthrow the rule of the former. The world of Lyrius is built around 4 bases, while the surface of the planet is characteristic for its diverse landscape. Both groups can field land units, as well as air and marine forces, while separate units fight on the planets orbit.
The game is a PvP-only title, introducing huge maps that take place on the planets surface, as well as orbital space stations. Each map can hold up 256 players. To join the fight, the player needs to create a soldier by equipping him with a set of skills and equipment. The authors introduced a wide range of community features, including guilds and player-owned bases that can be reinforced with AI-controlled guards.
