Good News and Terrible News

To get the up and away with Linda ending you have to be fast bear in mind before the countdown is triggered if you do not use the remote detonator while the tyrant is chasing you in the underground waterways when the water floods you'll get washed away into thr sewer area that has a ladder leading up through a manhole to where the road where U.B.C.S. sniper Arnold (who might as well be like an overly trigger happy U.B.C.S. version of Barry Burton) is shooting from and the Apple Inn entrance is across from go there first and get Linda then take her with you the rest of the way Linda will follow you but she'll limp slowly unless you shoulder her its recommended to play as a Yoko type character since while using her crawling not only can she avoid getting hit by Arnold's 4th shot but she can also clear out the claymore mines and not take damage from them exploding while crawling that's more or less what I had to do to get that particular ending was a pain in the ass though not to mention to succeed I more or less had to use my other 2 partners as sacrificial human shields the whole way onward from the Apple Inn
