De_square: Some Asshole's first map ever! (Bomb planting)

Background story: Some people have been trapped inside a building consisting
of four squares. They are divided into two groups, calling themselves
"Terrorists" and "Counter-Terrorists". One day the Counter- Terrorists
rescieved some nice boxes from their captors. This pissed off the Terrorists.
They have descided that they want to blow up the Counter-Terrorists boxes!!!

Terrorists mission goal:
Blow up the boxes (with the bomb!)
--OR--   Kill all the Counter-Terrorists!!!!
Counter-Terrorist mission goal:
Defend the boxes until the time runs out
--OR--   Kill all the Terrorists!!!!
