How to write from an in-universe POV
If an article is being written from an in-universe point of view, then at no point must the article refer to related real-world topics, such as game titles or game crew. For example, if an article must refer to the events of Metal Gear Solid 2, it should be stated like: "During the Tanker Incident..." OR "During the Manhattan Incident...", rather than: "During the events of Metal Gear Solid 2...".

Similarly, do not use dates to refer to in-game events, unless used in relation to other dates. For example, "During the Manhattan Incident..." and "On April 30th, 2009, during the Manhattan Incident..." are both acceptable, whereas "On April 30th, 2009, Raiden..." is not.

Tense
Articles writing about in-universe events must be written in the past tense to refer to any in-universe events. For example, use "Snake infiltrated the disposal facility", rather than "Snake infiltrates the disposal facility". Events are invariably referred to with the past tense.

Characters, items, weapons and concepts (and anything else of similar class) are, conversely, always referred to with the present tense, even when writing from an in-universe perspective. Remember, however, that character biographies are sections in an article that talk purely about events in the characters life (rather than personality, views, etc.), and therefore past tense must be used for these.

Similarly, in article about an item, a weapon, etc., despite the present tense being used (as explained above) anything that no longer exists must be referred to with the past tense. For example, use "Outer Haven was the name of Liquid Ocelot's warship..." rather than "Outer Haven is...".

If only one instance is ever seen, always assume there was more than one made, unless there is evidence to the contrary. That way, general facts are written in the present tense, whereas specific facts about one instance are written in the past tense. For example, "The Solid Eye appears similar to a plastic eye patch" is a general fact, whereas "Snake's model also acted as a corrective lense" is a specific fact.

Whenever you are writing in the present tense (no matter what the article), always be weary of the distinction between general facts and specific events. For example, "The Solid Eye combines ENVG light amplification..." is a general fact and the present tense is used, whereas "The Solid Eye was destroyed in a microwave tunnel..." is an event and the past tense is used.

Note that 'trivia' sections are always written from a real-world perspective.
