It's like Mad Max, but not nearly as good!
To me, Wasteland Angel is an unfinished game. It plays adequately, but there are a lot of little physics glitches. There's a decent amount of content, but only if you want to do score attack and improve your overall score or rank. The graphics are okay, but not great for the time of release, much less now.
The core gameplay is simple but fun; drive around and kill bad guys. Most levels are defense missions: kill waves of enemies and prevent them from capturing citizens from the town. The towns have 100 people, if you destroy a capture vehicle before it leaves the screen you can get the citizens back, but you can also run them over. There are also boss stages, such as a giant napalm truck that you can only damage by luring it into trails of napalm, a secondary weapon pick up. There are also first-person bonus levels such as racing or survival. There's also a story told in snippets of dialog and motion-comic style cut scenes.
The game works reasonably well and has controller and keyboard support, but there were several areas where the physics bugged out, such as getting stuck on environmental objects. The hit detection needs work. The fact that there's a dedicated "flip your car over" button should tell you something. Seeing as the game is a few years old already I doubt you'll see any improvements.
In the end the game gets repetitive quickly, the controls are a bit loose, there isn't much variety in gameplay, and the story is forgettable. If you like score attack or driving around shooting baddies in small arenas, this may still be the game for you!
