(Revised Core Set Perspective)
A great addition to NBN's taxing arsenal.
This piece of ICE isn't meant to keep runners out as its strength withers at the sight of a mighty fracter. Instead, Wraparound is meant to save NBN one credit and get the same benefits as its neutral counterpart, Wall of Static. Battering Ram takes 2 to get past both. Morning Star is going to get past both for 1 too. So why use the Static Wall at all? Well if you know any Criminal players...
But, wait there's more! Wraparound is one of the first AI hate cards that beginners are introduced to in the Revised Core Set, along with Swordsman, costing Darwin 2 at 7 counters (Datasucker-less) and Crypsis 8. Unlike Swordsman though, this ICE's End the run subroutine still functions fine without any AI breakers on the board, making runners dig for that fracter ASAP. Meanwhile Swordsman becomes a minor nuisance to runners and loses its "ambush" the moment it's rezzed if there are no AI breakers available for it to slice.
In conclusion, Wraparound should be a x3 in any NBN deck and at 1 influence, deserves splashing in any other corp faction (with maybe the exception of Weyland who's already got plenty in barrier options). The 1 in rez savings may not seem like a lot in hindsight but it adds up, especially against Anarch opponents.
