Men In Black: Alien Crisis is based off of the popular film Men In Black, and is another one of those easy to complete movie games. Two playthroughs are needed as you will unlock the Elite Agent difficulty upon completion of Agent. Make sure you have access to two controllers in order to complete the competitive V.R missions located in split-screen. The game's story mode consists of eight chapters that can easily be completed in around 3 hours.
Step 1: Playing Through The Game
Play through the game and unlock as many achievements as you can. You will need to complete the game on Agent in order to unlock the Elite Agent difficulty. If you focus on getting the kills with specific weapons then you will come out to around 780G on your first playthrough. Completing the story will take no more than 3 1/2 hours and is extremely easy. Try to upgrade your weapons and attachments as much as possible to give you an advantage when playing on Elite Agent.
Step 2: Elite Agent Playthrough
You will need to first change the difficulty to Elite Agent by entering the "Extras" located in the Main Menu. Extras > Change Difficulty > Elite Agent. Go into Chapter Select and start completing the missions. You may not even notice the increase of diffculty from your Agent playthrough since it's just as easy, and will probably only find certain boss battles to be a little more difficult then the first time playing. All of your upgrades will carry over from your Agent playthrough so I you shouldn't have a problem with making it through the missions.
Step 3: Competitive V.R Missions + Mop Up
After completing the game you will need to finish off the competitive V.R missions. There will be 12 missions that you will need to complete for the achievement. All of your upgrades will be carried over from your other two playthroughs so I suggest finishing these last. You will need access to two controllers in order to beat these, but you will not need any other assistance from a friend. The second player will follow you throughout the missions so it shouldn't be a problem. Make sure you take a look at the "Duelist" and "Conqueror" achievements listed in the guide.
Use Chapter Select to clean up any other achievements that you have missed during your first two playthroughs. If you have taken a good look in the guide then you shouldn't have a problem cleaning them up.
Men In Black: Alien Crisis is another one of those quick and easy 1000
games which only contains a few difficult achievements. You shouldn't have any problems completing the story on Elite Agent. Just make sure you update your weapons and attachments while progressing through the game.
