Tex Murphy: Martian Memorandum

Point-and-click detective game set in 2033 San Francisco. You're Tex Murphy, a PI hired to investigate a professor's suspicious death. The case starts with one body but quickly expands as you discover multiple dead scientists—coincidence or conspiracy, you'll need to decide. Gameplay involves interviewing witnesses, collecting evidence, and solving puzzles to piece together what's happening. The investigation eventually takes you off-world to Mars for the case's conclusion. Uses a first-person perspective with VGA graphics typical of early-'90s adventure games. If you like noir-flavored mysteries with a sci-fi twist and don't mind dated interfaces, this delivers a solid whodunit.
