Now if you want to get the best gun in the game listen up. You need to beat the mission Destroy Gun Emplacements, You need to beat the mission in under two minutes, (remember there is a second part to this). I suggest you bring some good hover legs your choose, and the arm mounted grenade launcher. If you beat the mission fast enough you will be asked if you will help distract the union forces. If you do you will have to hold out for 5 minutes with never ending enemies so you might want a fast AC. If you do well you will get mail saying that you got the Karasawa.
If you want to have the head that BB has, listen up. You find it in Defent Naire Bridge, go to the edge of the first part of the bridge, then when you see a small beam get on top of it. Now if you can fly all the way back you'll see it near the front of the ledge but you'll need to recharge anyway. Getting back is up to you I still have a hard time with that.
In the level that is called "Safeguard Water Supply" in the third layer: Industrial Research, a part is located at the top of the dam. As soon as you start, take a right and the part should be behind the building in the middle of the dam.
Where:3rd Layer Industrial Research
Mission: Defend Naire Bridge
How To: Well, first of all you have to find this part, not just complete the level. Then once you reach the end of the first part of the bridge, there will be a ledge to your left in the middle of the bridge. Look inside the bridge. You will have to fly to the other end. You might need a strong booster for this. Once you get inside, the part will be laying near the edge. Press O to pick the part up. Your Computer Head will say, "AC Part Acquired."
In the mission where you have to survive 4 minutes until these missiles can be launched at the union base (this mission is accepted by in the mission where you take out the large gun emplacements and a chopper will come to take you to this mission but you got to be quick to destroy the gun emplacements and to get to the helicopter your consort also comes to so pick one that can withstand a beating and retune fire) after you survive the time limit get to the transport to leave the mission don't just stand around you also must beat this the first time you wont get the karasara if you go back after you beat the game . you'll get a mail from someone and you'll get it careful its somewhat heavy and you can use in with the tread legs too. it has 50 rds does over 1000 damage it uses energy so ammo don't cost a thing i use it my self it has a fast reload time too
On the mission were you must destroy Naire Bridge, destroy a couple train-like things before you complete the mission. then you will get an additional reward [6000 credits each] and mail saying how you went out of your way to help them and you will receive AC part KWG-HZL30 AKA spread-shot howitzer
