Depending on the game type, each level will be completed when you reach a specific kill, destroy all enemies or stay alive until a given time elapses. Frontline Commando makes the job easy as you can easily fire head shots with confidence. You can also use a sniper for accurate distant shooting or huge weapons to destroy many enemies at a time. But the disadvantage of such heavy weapons is you can kill a civilian, thus, leading to failure on a mission. Heavy weapons also makes the game easy as you can complete ascertain stage within a short period of time. The game is graphically enhanced to fit android phones, giving it a nice look on smartphones. In case you get stranded due to the toughness of a stage, you can call-up rocket launchers to finish the job.
One of the limitations of the game is major heavy weapons and protectives such as guns, armored vests and airstrikes can only be purchased. So if you don't have the cash, then such weapons cannot be at your reach. But for some people who are ready to pay in other to get the best out of any game, purchasing items on game online stores mean nothing. You can also get essential health kits only with premium Glu Credits. That's weird. Some says Frontline Commando poses technical issue on some android devices but I have not experience such.
According to some people, when high number of enemies emerge, the engine struggles to cope, and the touchscreen controls often struggle to keep up too. Using a sniper can only be helpful on a far distance but are almost useless when you are faced with furious enemies attacking nearby, though the distance varies with various android devices. Frontline Commando is a nice game. Feel free to try it out. Am certain that you would like it.
