As far as i know, there is no way to "boost" another player to lv 30...
The only way is to do main missions, and secondary missions...
And even if you do mission in difficult mode, you will not get more XP... it is a waste of time...
It took me 4 days, to reach lv 30... it is not really difficult...
4 days? I got my friend to level 30 in about 2 and a half hours. You were doing it wrong.Originally Posted by fced Go to original post
