Quite a few members are messaging me asking me to help them with their characters (get them to high level) and I don't mind assisting but maybe the rest can help with friends and such.
This is what I'm doing - I'm sure it's been posted before, but considering this thread is over 12 pages long (for me) it's nice to repost useful information now and again.
• Take your strongest character, team with 2 other guys (also strong - post level 30 - high end gear type setups) and then get 1 low level (friend who is new) to join your group.
• Team leader goes to mission (any mission) and everyone fast travels to team leader.
• Redo the mission on HARD or CHALLENGING (whatever you prefer)
• The 3 strong guys do the mission (rush through it), the 'newbie' stays back (if he joins, 1 shot and he will be dead, so its pointless he joins actually) he can follow once all enemies are dead in a section.
This works really well if you have a full team because the fuller the team, the more enemies come, the more enemies, the more score the newbie will get.
Newbie must pick up everything
• You do mission to mission doing the same story as above - you might even finish the game - the newbie can redo all missions at a later stage if need be and follow the story accordingly.
By now, depending on how full your team was, they should go to level 23 at least - maybe even much higher.
You not done yet!
• Same story with safe houses... goto each one in turn, newbie follows you to it (via fast travel) and this 'opens' each safe house.
• Once there, he chats to JTF officer (to get missions) and reads map (for all the resource missions) and then once done, you goto next safe house - follow a pattern (from left side of map, down, under DZ, to the right, then up to the last safe house so you don't miss any)
• At the end, all missions should be open and the newbie can do the rest on his own.
I did this with only 1 guy helping me (my 2nd character) and I managed to get to level 23 in 2 hours - had I had more of a team, I probably would've gotten to level 26 or higher.
I had alot of high end gear as well.
While doing this, newbies can pick up alot of high end guns and equipment - but what you don't use, don't sell everything, find a happy medium between deconstructing and selling items.
Hope this helps...
