tower raid, filled with cheaters?

i wanted to test out the Tower Raid. i already hostet some lobbys already with ppl joining etc.

nothing seemed unatural.

but then i joined another players lobby . legend lvl 300 . after 2 stages i was sure this guys was hacking cheating whatever u wanna call it , he held shotgun and run through the floors to the next elevator . so i left ,

next lobby was also the same , shotgun ran from floor to floor with some handgun, it felt like it was endless ammo.

also checked both lobbys players . ( their steam profile ) one had 32 hours legend level 300 .The other lobby host was arround 130 hours legend level 300 and the difficulty of the Tower dropped drastically. even it was just for 2 floors .

they were gunz blazing through there ( unlimited explsovies aswell what i witnessed). then i joined a 3rd lobby and it was normal again took about 30 min to clear etc.

what is the fun in cheating if u buy a new game and have 32 hours in it just to cheat ? if u unlock everything or have unlimited resourcess anyway whats the point in playing that game ?!
