why cant i download the frontlines: fuel of war demo then? it is listed as teen on the marketplace.

also, does XBL update what you can download when you have a birthday? i made my account when i was 16, and now im 17, so does that mean i can d/l M and RP stuff?

if you use weapons that your character is trained in, you shouldn't have a problem with accuracy. you wouldn't want to use a shotgun if you're an infiltrator b/c they are trained in pistols and sniper rifles. the guns you have skill points invested in will be much more accurate than those you are untrained in.

turgore, you can train in assault rifles on your adept, but you need to unlock them first. for example, by putting points into pistols you can eventually unlock and be allowed to to train in sniper rifles (i think its pistols, cant quite remember). then you can put your points into snipers and get more accurate/more damage. i dont know offhand which weapon unlocks assault rifles, but just using them won't make you accurate
