Well packed and done not as sofisticated like GTA but stil it is 3D Action pc shooter with lots of extra points!
Total Overdose is a very good "script game" and usually the missions are interesting and very well scripted and fun to do, but its not a "freelancer" game like we "used to in GTA BUT ITS NOT GTA!!!...although you CAN walk in the city, you can even run :) but the areas are very small and the map is divided to areas like the "port" or "Los Angeles" that you can reach after you go threw a loading screen.
The most annoying thing that should be fun is the "cars" thing....the control of the car is very difficult and "glichy", not accurate and sometimes STUPID. For example, when you "meet" our beloved friend "Mr wall" the car sometimes stuck there and you have to do a reverse even if you are not in front of the wall, it happens even when you touch it. It makes the races missions not as fun as they should of been.
The bullet time is very useful and many missions are based on this skill. You can learn some tricks in a special school. Big arsenal of weapons also available.
Although this 3D shooter can be sometimes annoying but be not fooled its very well packed mission based 3D shooter, the Mexican theme is a plus point....
enjoy....not from my English...from the game :)
