kill em all....easyest way to go about it

just keep shooting the invisible man
agan and agan, its best to have lots of
health on you and a good gun.

just have a type of shotgun and let it get close and... BOOM!!!

this is the easyest way to kill this invisible man...
just run until u hear the grrrooarr of this monster... then
go back to the entrance of this room, military is going to kill this guy, if not, this guy
will kill all the military guys, just dont go to this room while they are fighting cause
they will kill you first... if u cant go through this, u will never finish this awesome
game n00b!

Try getting arrtefacts and wepons that u dont need the buy something useful like
shotgun,armor,and ammo then go 2 the sewers and try to get bloodsukers attenchin (sorry
bad english) and run back to that door it wont go p*** the door then when it goes back
where it sleeps he runs very fast TRY TO SHOOT IN THE BACK

need more help go to gmail my mail is Jegor.Cuhnin@gmail.com

thank you for the question

Arm some grenades from grenade launcher and throw grenades.Be sure to also have
higher-powered weapon like shotgun or AK.When you get to sewers,use grenade to kill all
soldiers,and then throw/shoot 3-4 grenades on monster.If you run out of "Artillery",use
your stronger weapon on monster.You will recognize monster by it`s cloaked body.Search
it`s body and you`ll find something really good!
