Thats more along the lines of what I mean. Not necessarily a section where you mow down Aliens with a pulse rifle or anything like that. Perhaps a section where you need to fend off multiple aliens with a shotgun or a flamethrower as they come at you relentlessly and hiding isnt an option. I didnt stop sneaking around at the end though. Even when there was two aliens hunting me. If id just gone at them with all I had I think id have ran out of fuel and items quickly and found the last few areas much harder as a result. This game never forces you to go on the attack ever.
Edit: What is cool about this game though is that while it doesnt force you to become more aggressive in your case you felt you had to. Just like Ripley at the end of Aliens with the flame thrower. At that stage in the game, similar to Ripleys attitude in the film you thought "you know what, f**k this, I need to get the hell out, right now, alien or no alien. Ive got my flamethrower and a couple of pipe bombs. Lets do this...".
