idea for mutant mode map

ThaGza

just a shot in the dark but i think it would be sweet if you unlocked some upper levels in zone13 like when you walk up the stairs into the building behind the street light post
and behind the stair case and windows there is another stair case but it is flagged off
would be cool if it were opened up into another level maybe add some more hiding spots and create like a walk way ontop of that roof that everyone trys to jump up to
and then continue it into the next building accross from it just some more area to run around and try to evade the mutants since they win like 100% of the time
