What about Cold Front but the frozen wasteland part is extended by 20 times.

itemtest

Yeah, doublecross, maybe.

ctf_well

How about the map that has the big ol' tower that the cart goes up and around, but the tower is like 20 times as tall.

What about plr_highertower?

ctf_quadruplecross

ctf_well with 20 rail crossings and 20 wells

Hightower but the tower is x floors higher and the elevator on the last point is x times higher.

hightooooooooooooooower

cp_cloaaaaaaaaaaaaaaaaaaaaaaaaak

plr_reallyreallyreallyreallyreallyreallyreallyhightower

plr_hightower but the bomb explodes and respawns each time you go near it so nobody can cap
sd_dooooooomsday
pl_badwater that's full of bad water that kills you
cp_dustbowl with even more choke points and imbalances

Also every map's healthpacks should explode if you touch them.

idea
ctf_double_fort
the road part of doublecross + the fort part of 2fort
