1. The Architecture of Project I.G.I. 1
Project I.G.I.: I'm Going In is a 2000 tactical first-person shooter by Innerloop Studios. This page indexes 21 format-guide topics; it does not make claims about engine lineage, hardware requirements, or runtime loading behavior.
The guides cover binary formats represented in the repository's research, templates, and parser implementations. Where sources do not establish a format's runtime role, the guide states that limitation.
2. Index of 21 IGI 1 Format-Guide Topics
The index groups 21 format topics. Individual guides identify which layouts are described by repository templates or parsers and which semantics remain uncertain.

3. Format families
This diagram groups the guide topics by their documented role. It is an index, not a claim about runtime load order.
4. Scope of this index
The 21 rows above are guide topics, not a claim that the games contain exactly 21 distinct binary formats. Some topics group related extensions or describe engine data without a single dedicated extension. See the About page for source links and how evidence is classified.
