The maximum score you can get in the patched version of the game, is v10.0.3. That's for finding all the build notes and completing all the mission objectives.
Some objectives are optional or sometimes easy to miss. Some things that players often miss are:
Spoilers follow, highlight with your mouse
- Completing the training on the first level to get the initial v1.0.5 score. (The disc combat training can be skipped without losing points, however.)
- Not looking for build notes between all the races on the Light Cycle Arena and Staging Pit level.
- Talking to the ICP listening the the Light Cycle race coverage.
- Talking to ROMie before releasing him from his cell, in the Prisoner Bin level.
- Missing one build note in the center corridor near the end of the Primary Digitizing level, which is easy to miss because of the time pressure on you due to the format wall. But the build notes are placed in the level in a semi-random fashion each time you play a new game, so sometimes it's there and sometimes it's not.
- Not saving all the towers from corruption on the City Hub level.
- Not looking for build notes between the different stages on the Firewall level.
This is just a FYI, in case you or anyone is wondering what the maximum score is and some tips on how to reach it.
