Its a really addictive game although it does have some flaws but all that I look for in a game is fun, enjoyment and usefulness.
Ive used it for a really long time and its always fun when you compete with humans rather than just the CPUs or the machines.
1) -It does not have any kind of concept.All it needs is a wi-fi and a hotspot.
2) -Its a relly old fashioned theme and animation so theres a lot to improve on the graphics
3) -Has quite a few numbers of venues to fight.But some more new areas and newly introduced guns and ammunation would be of a greater value
4) Good and addictive game. Is quite fun.
