The Matrix Online

Easy experience:
----------------
- Set missions for Tiny/Hard. The missions will have enemies at
one level higher, but you get more experience points.

- Get a team together and be social. Team up with someone at a
higher level (the higher the better). Use Tiny/Hard missions.

- Take your time. Take an extra minute to scout the entire level.
Missions are timed; the longer you take, the more experience points
you get.

Shogo reference:
----------------
In the international district, there is a club named "Club Shogo".
Shogo is an earlier Monolith game, a first person shooter, that
was made before they were bought by Warner Brothers.
