Alien Shooter How to obtain the BFG or Alien gun

iv’e seen lots of tutorials on alien shooter on how to get the BFG but i never get them working on my game but iv’e found a solution that worked for me

1. make sure you have a save that has the first lvl completed and is on lvl 2
2. go to steam right click on alien shooter and browse local files
3. go to the saves folder and open the saves config file
4. now this stuff is hard to read sometimes since its all jammed together but what you need to change is under the save that you named should be a text line called PlayerWeapon0=0 now what i did was for every save i changed it to PlayerWeapon0=1 now the best thing you can do is read the texts line from line just to make sure it changes the file after that click CTRL and S at the same time to save the file
5. now go into the game load your save and you should have the gun
WORD OF CAUTION
when using the alien gun it takes away 10 HP each time you fire it so watch ur HP when using it
