Thanks for making me reconsider the Vulture. It's a totally different game compared with using sentries.
I find it harder in the first two areas and never had much success with it before so I decided to try it using only two relics, Mortal and pistols only. I escaped; nothing amazing but I am happy with my score of 216,318
I needed a few games to adapt my play style but once I got to the Cabin area... WOW! what a difference the vulture makes.
I can hardly wait till the weekend to try Solo five relic runs.
