Tweak the damage of weapons for more realistic gameplay and fun ; ex : now when you hit 1 ammo with your Shotgun in the Lambda handroid's face it down . Head-shoot is possible with pistol too . CAC improved , melee weapons can protect you ! Flame-Thrower :Lower the fuel_units_consumed_per_second to 1 ; now you can protect yourself more longer ( don't worry , the alien always killed you a lot ;) Crafting improved with nightmare difficulty : in nightmare's difficulty the resources is lowess ; ex : now when you craft 1 noisemaker , you craft 9 of all gadget you have the blueprint ; enjoy playing in nighmare difficulty with lot of stuff ! Amanda Ripley's Health increased ! ( More chance to survive when the lambda catching you in nightmare difficulty ) I've Also tweak the stats of Lambda and human both ( the human can one-shot you in certain area , now you can Fight ! ) PS: There is another type of Lambda I can't found the stats ; they look like the same but much more resistant !
