: The theta error is described in the Marathon manual as a manufacturing
: defect, which is plausible if the weapon we're using was perhaps a clone
: or "shop model" made by Martian rebels/separatists and hidden in
: the Marathon and/or eventually added to its security inventory. It seems
: to me that a military-grade weapons manufacturer wouldn't have made so
: many rifles with such an obvious flaw; perhaps given the layout of Mars
: bases, space stations, and the Marathon itself, which are really only
: tight corridors or expanded enclosed spaces, it made more sense to have a
: repeating rifle that was more effective at clearing things at close ranges
: than shooting accurately at great distances (which the grenade launcher
: seems better suited for).
I actually loved the inaccuracy of the AR, because it was great for running and gunning. I could still hit something without worrying whether I was aiming directly at it. It may have been for this reason that I found automatic weapons in other FPS games so annoying.
