Phoenix Point One Year Edition released! Phoenix Point Geoscape December 8th, 2020 Phoenix Point, the successor to the XCom series made by its original creator, Julian Gollop, has just released its one year edition on Steam and other gaming platforms. The player takes control of Phoenix Point, a top secret organization created to deal with extraordinary threats, as it fights the Pandora virus, an alien lifeform that wishes to remake Earth at its own image, while dealing with human factions that also have their own agenda for the future of the planet, in a game heavily influenced by the Cthulu Mythos. The game follows the classic 4X (Explore, Expand, Exploit, Exterminate) for its Geoscape layer, with a turn-based combat system situated halfway between the original game and Firaxis' XCOM: Enemy Unknown. Phoenix Point even has its own wiki and it seems influenced by the UFOPaedia! XCOM: Chimera Squad announced! April 14th, 2020 Firaxis has announced an upcoming spinoff to the XCOM franchise, "Chimera Squad", to be released in April 24th. The events of the game take place 5 years after XCOM 2 and are centered upon the titular multi-species law enforcement unit keeping the peace among the humans and aliens living together in the metropolis known as City 31, as a seeming spiritual successor to X-COM: Apocalypse. The released gameplay trailer reveals that in addition to playable alien squad members, consisting of the Sectoid Verge, the Viper Torque and the Muton Axiom, the game also introduces a Breaching mechanic for setting up an opening surprise attack at the beginning of combat, a Timeline system where the combatants on both sides individually take turns after each other in a fixed, faction-alternating order rather than the entire team acting as once like in previous games, as well as disposable androids to take the place of injured agents on the team roster.
