I used to play it before 1.7, but that update causes the game to crash after a couple minutes, so I don't bother anymore.
Are all the games like 5 min ordeals, with 3 objectives or less?
No, most of the maps are 8-10 minute affairs - with the exception of Insurgent_Camp and Weapons Cache. The other maps were so boring with all the waiting around that I didn't bother to play them.
Is cheating rampant in this game?
I don't know.
How do you get honor points back after you lose one?
Be on the winning team, camp, get kills, don't die, don't TK your teammates. You get an honor point added whenever you have accumulated X number of points (the ones that showup on the scoreboard when you press F1).
Any newbie advice?
The M203 is insta-death, the best weapon in the game.
