Yeah, I want a free roam first person of Aliens (just like in AVP2 game) so that players can get the feel of being an Alien. And I want the setting to be a city.
And the Aliens can hide behind the shadows (dark alleys, shadowy corners and etc.) in order to avoid being spotted by a group of humans which adds in to the excitement and tension just like in Manhunt 2, Aliens must stop their breathing so that the humans won't hear when they check to see if the Alien is really there.
Sure, an Alien can tore through a small group of enemies, but if it is a majority then the Alien would be outnumbered and easily shot into pieces by them. So hiding behind the shadows is an essential.
