spawn_zone n death death 100 100 10 0 0 0 false 1 0 0 5
spawn_zone n target1 target 200 200 5 0 0 0 false .1 .2 .3 5
spawn_zone n target2 target 205 200 5 0 0 0 false .1 .2 .3 5
set_target_command target1 onenter collapse_zone death
set_target_command target2 onenter collapse_zone death
This should successfully create zones that collapse the death zone named "death"
I would suggest making 2 zones with this command right next to each other to make sure it works (each zone will have one use)
#EDIT# I've just tried this. Seems to work fine
If you want to do this from the map I would suggest using delay_command (make sure the delay_command access level is higher than the settings)
<Setting name="delay_command" value="r0 1 spawn_zone n target1 target 200 200 5 0 0 0 false .1 .2 .3 5">
<Setting name="delay_command" value="r0 1.2 set_target_command target1 collapse_zone death">
etc...
