The first already contains the most important facilities and a little open space while subsequent bases begin as only an entrance, with additional facilities needing to be built for the base to be useful. These are able to engage visible UFOs within their range and thereby help with difficult interceptions.īase Management Construction Ī base exists in a 5x5 grid of underground construction area.
UFO ALIEN INVASION DEVELOPOR VERSION INSTALL
In addition Phalanx are able to install anti-air weaponry at bases and off-base SAM sites. Landing sites may be approached with a dropship for a mission the same as crash sites, except there will be more surviving aliens to fight, more salvageable equipment and a strictly limited time frame before the UFO takes off and escapes to orbit. A UFO crash site will only result if the craft was downed over dry land and UFOs will sometimes decide to land before they can be intercepted. Once craft are in weapons range, they can begin shooting at each other until one flees out of range or one or both are shot down. UFOs may also decide of their own accord to hunt down Phalanx aircraft in the vicinity. By clicking on a UFO the player brings up a list of available aircraft and chooses which to send after it. This also applies to aircraft.ĭogfighting takes place directly in the Geoscape-there is no separate interception minigame. Additional base construction can be ordered from here and facilities can be built if enough bases exist-each supports only a fixed number of external facilities and there is a global maximum as well.Įach Phalanx radar system has two ranges: A smaller detection range within which UFOs will be found, and a larger tracking range, within which already detected UFOs can be followed.

Bases, external facilites, even such things as UFO crash sites. The Geoscape lets a player see all facilities represented on a globe. The game then enters the Battlescape mode, a turn based tactical fight against surviving alien forces on site. When aliens are shot down (or land), the player sends a squad of soldiers to secure the crash site. Aerial dogfights between human aircraft and alien spacecraft take place in Geoscape mode, as well as new facilities and bases being built from there.

In the Geoscape, the game plays in real time (with optional time acceleration). The single player campaign is primarily split into two parts which are played alternately.
UFO ALIEN INVASION DEVELOPOR VERSION HOW TO
The player starts out with standard ballistic weaponry and combat armor, and must decide how to proceed with research priorities such as obtaining and interrogating live aliens and developing man-portable laser weapons. With much of their advanced equipment proving vulnerable to alien stealth, Phalanx initially makes heavy use of ancient, dumber weaponry systems as well as advanced electronic countermeasures and targeting systems to try and reduce the aliens' advantage. The game begins in the year 2084 shortly after the aliens attacked first Mumbai and then Bonn, Johannesburg, and Bangkok, inflicting heavy military and civilian casualties with little effective resistance.Ī mere 18 days after the attacks begin, the player takes command of Phalanx, a hastily formed extraterrestrial response force under the UN which is the resuscitation of a long-defunct program of the USA.

In the backstory, the world went through a chaotic early 21 st Century, which stabilized in the latter part of the century and led to a period of peace and relative prosperity.
