The game has a difficulty of 4/10 because the game isn't hard, but some parts are a tad bit annoying. The game is short, but you have to play it 3 times because there are 3 different characters and you have to basically beat the game with each of them.

Introduction:
This game isn't that great of a game. It is a copy of the Call of Duty series and has many glitches. This game can be fun, but the levels are way too short and the game is somewhat glitchy. There are no cheats in this game. You can play on any difficulty, but easy is advised so you can just fly through the game. There 5 glitched achievements, but they are not any harder to obtain. "Good Citizen" is glitched in a way that makes you not need to host 30 hours of playing, you only need to host 3-5 hours. "Play all Multiplayer Modes" you have to host and play all multiplayer modes. "First Place" you have to host and win on all multiplayer modes. "Last Second Hero" you cannot be the host. "Whites of Their Eyes" you cannot be the host.

Abbreviated Walkthrough:
There are some hard levels in this game, but just follow the achievement guide and you should easily succeed through the levels. Some levels are harder than others, but if you fail, just keep trying and make sure it is on easy. There are really only 3 hard levels and here is a walkthrough for all 3.

Maelstrom: - Part 1: This level is right after "The Net Tightens" and it is when you have to drive the tank once again. Do not worry, I have an easy way to beat this. To start off, be Bull because his sniper is needed. Start the level and ignore the tank and kill the first 4-5 guys walking around. You will now get a teamate who helps out for a little bit. Turn right around the corner and snipe the guy on the balcony with the rocket. Walk foward a little and before the intersection there should be a little room to your left, go in there and switch your pistol for that rocket, now you can pick the rocket ammo from the guy you sniped. Go around the corner and sneak up on the tank, 2 rockets will destroy it. Snipe the rest of the enemies and check every corner. Now go back to the tank and go to the large door where you destroyed the tank, kill any enemies that might come through now because they have rockets.

Part 2: Go forward and take a left (while in the tank, never leave it behind or it will be an instant fail), hide behind the building and get out, kill everyone on the ledges around you, get some more rocket ammo and kill the tank and the rest of the enemies. Check every last corner again before getting into the tank. You should still have full health in the tank. Proceed through the doors.

Part 3: This is the final part and you have to be quick at the beginning. Enter the third area and with the tank kill the people to the left, then to the right, then whoever is left.  DO NOT move too much in this process, your tank should not take to much of a beating. Try to park it in a safe place, but this will trigger enemies to attack you and you will have to get out and make them target you. Blow up the first tank and kill the enemies around you. If you keep walking forward, on the cliff should be a rope for Bull to climb up and get to the top of the cliff, take your time finding it. Once you get up, snipe off some enemies and pick the rocket ammo up up there. If you hear gunfire or anything, stay up there until you kill them, you should see about 2 tanks, blow them up. Now get down and walk everywhere you can and check every last corner. Walk to where you would end the level (big door) and try and trigger the final targets, should only be one. The final target is usually (while looking at the big door) to your left, they have a rocket so be careful. Shoot the tower and they should die, if you have 1 target left, shoot the big door and the level should end, if it doesn't, look around some more and then go get your tank and drive it carefully and cautiously to the big door, shoot the door with the tank and it should end the level.

Clash of the Titans: This level isn't really that hard, just stay in cover and watch your back. Try not to stand up, crouch around cover. Follow what the directions are because there is only 1 checkpoint in this big level. Once you do get the checkpoint, it is all downhill from there. Do as the directions say and when you have to take over the city hall building, try to jump over the tank to make the level shorter and safer, take out the enemies shooting you, and after about 3 enemies try and hide in a safe spot away from where you just were and the level should end.

Total Victory: I recommend using Ross for the final level of the game because he can take more damage than any other players. Also, somewhere in the final level is a shotgun, switch the shotgun for you pistol and try to save as much ammo and grenades as possible for the final part of this level.

Online Achievements:
For online achievements, you will need to find a group of 6 and boost these achievements, that is the only way to really get them. Almost all online achievements appear when you finish the match, and you can sometimes get the "Kill Count" achievements in multiplayer, but they require well more than their published requirements.

Conclusion:
This game has a horrible rating and it is pretty glitchy. The achievements are easy, but if you are missing any by the end of the game, just do what the description says.  You should unlock all the "Beat this Mission with..." while playing with all 3 characters, and you will, no matter what, get 500 kills by the 2nd playthrough if not the 1st. If you do not care too much about achievements and just want to play a game, this is the game for you. If you like getting a good amount of achievements or are a completionist, than this game is a quick game as long as you have a boosting group ready.
