I suggest that he plays the tutorial for both monster and hunter. At least a few times each or until he gets time score of under 6 minutes. Then he should watch both the beginner and advanced video tutorials that are in the extras for all the hunters and monsters. Then he should play each hunter at least once on solo and try out each of the hunters’ weapons and abilities out. Playing solo mode can speed that part up because it allows one to switch between hunters. It is important for him to know strategy but if is more important to be able to use the hunter or monster that he will select.
The hunters that are very popular are [[All hunters are great. I only listed the ones that are popular and you should still try the other hunters. Surviving is based on teamwork, positioning and jetpack management.]]
Medic: Slim, Val
Support : Hank, Maybe Sunny
Trapper: Wasteland Maggie, old popular choices were maggie and griffin
Assault: All the Assaults are really good but depends on play style (this is the same for other hunters but assault can pick )
Watching gameplay videos after all of the previously mentioned will help strengthen his evolve skills since he will better understand the way the game works.
