anyone heard of a game called alien shooter? its a shooting game on the pc where yo obviously shoot and kill aliens...okay... so he had this game for ages and started playing it yesterday...he gets inside the 2nd screen, inside the building? and he cant find his way into the next room...he killed all the aliens, turned the power on... and even found 2 secret rooms... but he still cant get anywhere from there...i tried googling a few guides, to no avail, gamefaqs and gamespot doesnt have any of those too...can anyone help? he said its just this room... thank you... T_T

I did a little research for you and came across this game on my fav video game web site. I'll give you the link so you can see if this is the game you are looking for.http://www.gamewinners.com/Cheats/index.php/Alien_Shooter
