Episode Four: The Final Fight has good level design and gameplay. A lot of stuff is hidden, keys included, so be sure to check everything that might open, be a switch, or blow up. The placement of the hidden objects is logical for the most part so if you have to fight your way into a building or a specific room and you don't see anything out in the open keep looking. There is a good balance between the aliens and health and ammo you can find. Level 1 is a building complex with lots of passageways and tunnels connecting the buildings. It took me almost 40 minutes to finish. Level 2 is a city and sewer style level. I did better with this level. It only took me 18 minutes. Level 3 is a city and subway level. Level 4 is another city level. I rate this TC as good with 3 out of 5 stars.
