sorta, with the way marvel rewrites history on a weekly basis its hard to pin down.
so far, it didnt really enhance his powers, just gave him a neat costume, but it also started to mess with his mind (he would wake up web swinging across the city). he hit up reed richards who discovered that the costume was alive, and wanted to bond with him. he freaked, they got the alien off, it landed on eddie brock, made him venom (and spidey blind to venom danger via spidey sense), and gave brock most of spideys powers.
apparently now though, the suit gave eddie cancer, and its an adrenaline junkie, and it eats people, and was in antartica (sp?)
dont ask me, i dont friggin know.
in the ultimates universe, it started out as a project peter and eddies dads were working on as a "cure all" suit, but when peter tried it out with his newly messed up DNA (suit was keyed to parkers DNA, daddy, not kid), the suit freaked him out, worked as a costume for a little bit, went haywire, absorbed eddie, was hit by lightining, dissappeared. also, part of the suit was being tested on by doc conners, and it escaped, became carnage, killed a lot of people, and pretty much ruint spideys good fun happy time days. oh yea, it killed gwen stacy too.
shes in the new film, so expect her to buy it. she didnt last long in the comics (either main universe or ultimates).
but, back to the idea of the poster. its interesting, but it really isnt a good "teaser" poster. after spidey 2 (where peter cried in almost every scene we could see his face), seeing a depressed spiderman doesnt really make me wanna go see the film. sin city's look worked for sin city. it doesnt work for spidey. least not for me.
