Also to mention as with other upgrades of this type it’s not available until day of release, i.e. you can’t pre-order the upgrade,
I had a further play of UC1 last night. It’s still good fun and the shooting is particularly great at 60fps - I was popping heads all over the place - but the mechanics for traversal have aged quite badly and it feels clunky and frustrating. So I’m going to move on to UC2 to see if I can work with the improvements they made there.
