Call of Duty: Modern Warfare and Warzone Season 5 arrived with a lot of new material: a new operator, two new weapons, etc. The most exciting part, however, is the train that's now traveling through Verdansk and the opening of the stadium.
Ever since Roze blew up the stadium roof in the Season 5 trailer, we've been able to enjoy the loot and the intense shootouts of the stadium's insides. Along with that, though, has come a serious exploit.
Stadium Walls aren't Safe in Call of Duty: Warzone
The invulnerability bug in the stadium isn't particularly new. Months ago it was possible at certain places in Verdansk to slip into walls and take out other players from there without them being able to see you or hit you.
We thought that annoyance is behind us, but this exact same glitch now seems to be reappearing at places in the stadium. Several players reported that they were shot at from columns or walls without being able to see anyone. Even Call of Duty League commentator, Joe "MerK" DeLuca, has been properly introduced to the new/old exploit:
Players who slip into walls are not visible to other players, except for a small piece of their weapon that is looking out of the wall. Also, they cannot be hit, which makes it impossible to defend against them. However, it seems that if you take advantage of the exploit, you have to stay inside the wall for the entire match. It is possible to get in, but not to get out, which is... it makes you think about life.
EarlyGame Tip: If possible avoid the stadium for now and wait for the next patch from Infinity Ward that will hopefully take care of it. Leave them suckers stuck in the walls forever and repent for their sins.
