Slam Attax is a WWE-licensed collectible card game published by Topps Europe, first released in the United Kingdom in September 2008. Modelled on Topps's Attax format, the game assigns each WWE superstar an Attack and Defense rating out of 100, and gameplay broadly resembles a heads-up comparison mechanic similar to war. The inaugural set contained 121 cards covering Raw, SmackDown, and ECW brand talent alongside WWE Legends and Divas, with starter decks of 40 cards including foil Finishing Move and Championship Belt cards and a printed playmat. Success in Europe led to multiple follow-on editions: Evolution (2009, 197 cards), Mayhem (2010), Rumble (2011, 226 cards), Rebellion (2012), Superstars (2013), Rivals (2014), Then Now Forever (2015), Takeover (2016), and a 10th anniversary edition in 2017, with a Chrome edition appearing as late as 2021. The product was produced primarily for the European market and achieved broad retail distribution through newsagents and supermarkets across the UK and continental Europe.
