It's a very simple map, in fact, my very first.

1. Collect the gun and ammo from the sofa.
2. Ask Barney to join you in the arena.
3. Proceed to the arena through the sliding doors.
4. Fire at him once. Try and dodge his bullets.
5. When you get bored, pwnz him.

Future additions may include monster pens, where by you open the pen, let out the monsters and kill 'em basically.

Please note that this is my first map EVER. If you enjoyed it, please rate it, leave feedback or even visit my site.
