javihyuga: I remember that these little fuckers scared the shit out of me when I was a kiddo so much, I could not play the alien game on my PSX.
A few years ago, I was man enough to go an play an alien game (this one, before it was available on GOG), but everytime I heard the "taptaptaptap" of those tiny legs, I could not but start throwing rockets at the floor, creating a mayhem of fire and smoke. When that deadly fog fade away, the upside corpse of one of those face fuckers remained there, quietly. I spent another 2 mags into the corpse to ensure its dead state, and proudly teabagged that asshole.
The pride faded away when I realised I had wasted all my ammo on a shitty asshole and had to restart.
How you survived to the radar sound? When was children I was able to finish the PRedator levels, half of the aliens (got very dizzy that time and now) but not the marine... creepy radar.
Anyway, for the original question, flamethrower is very useful but probably the grenades are a better idea (IF YOU see the eggs)
P.d. but the people who got worse time with the Alien franchises... the one who had to remove the eggs from the film set (They were made with organic part and were forgotten in the set by months, so, the smell had to be SPECIAL)
