Citizen Abel was a nice little level, the sequel was a big improvement, though it didn't feature much gameplay so I wasn't as impressed with it as I could have been. Citizen Abel 3 takes place before both of these, and it's easily the best yet. It starts off with Abel being launched towards Stroggos, however things get out of control and you're left to fight for yourself. Eventually you make your way to the Big Gun where the Stroggs are running the show. Obviously, your plan is to destroy it.
Citizen Abel 3 is again not your usual Quake2 release. Brendon has further developed and improved his unique style of not having the typical tough and fun map, but instead telling a story. This level reminded me a little of some of Neil Manke's levels, with that unique perspective. There are many cutscenes/demos, and many F1 updates. You can even read the logs from poor dead soldiers.
Level design is also rather different - Brendon really pushed the idea of you being on another planet with the stars above and often darkness all below. When you get on the Big Gun, you don't want to fall off the side. Much of it takes place among terrain, cliffs and destroyed buildings. All was made very professionally. The only weakness in design was that lighting was a bit bland at times.
Don't let the fact that it's 20 levels make you think that it's going to take a long time to complete. There are probably less than 50 enemies throughout, and the levels aren't that big. It will take you a while though, at least an hour. And it's great fun all the way. This very unique release I really enjoyed and I hope Brendon continues mapping with other games (this was his last Q2 release probably).
