map06: the spider mastermind wont shoot back, seems trapped on sector
mismatch. FIXED, made spider platform larger.
map10: fixed map with new ammo and monster arrangements and exit.
map13: needs finished or replaced. Only added an exit, and made skill
more sane.
map14: needs most sectors unjoined. FIXED, maybe. Much more noticeable
in coop with random sectors and HOM.
map24: needs skill adjustment FIXED,
