I have the slingshot DLC, but im pretty sure it wasnt there, possibly because i didnt enable it when starting the game. Looking at what it says about the DLC on steam, i dont recognise it.
If i did The Long War, will it still have everything from EW in there, the different arcs etc? Im just thinking it doesnt feel any different and i'll either come back to it in a month and do it again, or maybe skip EW and do the TLW version. As i mentioned, ive done the first half of the game a few times, getting to the point where you need the key, and then stopped there. This weekend is the first time ive gone beyond that, so another fresh start doesnt feel all that great. I probably should have just gone from EW to begin with, but i went with EU thinking they were 2 completely different games, so do them in the right order, rather than EW then EU and know how much its missing that i liked.
The Meld is something which is different, thats about the biggest thing ive noticed so far, but i havent been able to use it, but im guessing its very useful later on, and like you say it becomes a real challenge to get to it in time. Im going with Classic mode this time, last time i did normal and once i had my satellites up, it wasnt much of a challenge. So much more funding made it easier to give everyone the best items.
edit: I've also noticed im pushing into a map much faster, rather than short move w/ overwatch, because of the need to get to the meld locations ASAP. It kinda screws with you, slow and careful but lose one meld pickup, or charge in head first.
I'll carry on a little longer, hopefully it'll open up a little, otherwise i might take another break from it.
