Source-derived summary

Half-Life 2: Episode Two is a 2007 first-person shooter game developed and published by Valve. Following Episode One (2006), it is the second of two episodic games that continue the story of Half-Life 2 (2004). The player controls Gordon Freeman, who travels through the mountains surrounding City 17 to a resistance base with his ally Alyx Vance. Like previous Half-Life games, Episode Two combines shooting, puzzle-solving and narrative elements, and adds expansive environments and less linear sequences.

Episode Two was released on October 10, 2007, for Windows on Valve's distribution service Steam, and as a part of The Orange Box, a compilation of Valve games for Windows, Xbox 360, and PlayStation 3. The PlayStation version was produced by Electronic Arts. Episode Two received positive reviews.

Valve canceled Half-Life 2: Episode Three when they abandoned episodic development and began developing a new game engine. In 2020, after canceling several further Half-Life projects, Valve released Half-Life: Alyx.

Gameplay

As with previous Half-Life games, Episode Two is played in the first person as Gordon Freeman against transhuman troops, known as the Combine, and other hostile alien creatures.

Editorial summary

This brief starts where responsible research should: with the source description of “Half-Life 2: Episode Two” as 2007 first-person shooter video game. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2007, 2006, 2004, 2020—that can be checked directly. The authority record carries competing date values—2007-10-10, 2007-12-14, 2010-05-26, 2013-05-10—which should remain separate until their references and qualifiers are resolved. The account is most persuasive where Half-Life, Episode and first-person can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as 2007 first-person shooter video game. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 15, 2026. The linked authority identifier is Q553308. VIAF identifies the subject as 294471171. 1 of 6 selected statements include explicit references; 4 carry qualifiers and 0 use preferred rank. The first chronological checks are 2007, 2006, 2004 and 2020.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
