Is my friend cheating?

I'v been away for one day and yesterday he told me that he found a new safehouse location for our new base.. today when i arrived (he was not online) the "base" look to good to be true.. he hade walled of a huge sektion around 4 houses and packed them with boxes for storage.

My friend and i have just started to play the game and rents a server..

But he is the type of guy that googles the best weapon in game runs though the entire map and gets it and then complanes that the game is easy..

He has not died for a super long time and has like max stats. one time when i got "bitten" and he said "ill putt you in god mode.. FFS :(

Your suppose to die in this game, it makes you try new stuff..

He refuse to admitt that he's been cheating.. is this even possible? for one day of playing?

is there anyway that you can look at the loggs maybe?
