OK through a glitch in co-op mode you can get unlimited
ammo/camo. More info is found on the HBO
(http:\\
halo.bungie.org) site, under tips and trick,
Keyes Corner. This is how it works: you know those
screens that come up part way though the levels (eg.
Warning: Hitchhikers could be escaping convicts & Fourth
floor, guns, tools, keys to super weapons) well if one
person stays back where there is the active camo pick-up
while the other goes to that line, if the first picks up
the camo, then the second quickly croses the line
forwards then backwards, the first's active camo should
stay. For Ammo the process is the same execpt the first
reloads while the second crosses the line, the ammo in
the gun will th deplete but the rounds wont when you
reload.

P.S. Sometimes it doesn't work, crossing back and forth
over that line should help it stick. Maps as to where
this can easiily be done are on the above mentioned web
site.
P.P.S. A similar trick can be done wioth eneimies, run
past them then cross over one of those loading zone, and
they forget htey saw you so you can sneek up on them from
behind. Works well with Hunters.
