ADG Episode was quite a challenge for me. There is a lot of shotgun ammo to be found but not much for the other weapons you get. Very little health on each level also. I spent most of my time around 30% to 40% health. There are lots of pigcops, and on level 1 two bosses to kill. The level 2 subway was not too hard. The level 3 plant was very dark and if you see a monitor showing a door or gate the switch is nearby. I'll let you find out the rest for yourself. My rating is 3 out of 5 stars.
