Dead Island: Riptide bonuses in the UK will include the Survivor Pack, which features the BBQ Blade seen above. The hefty machete has a fuel tank attached that, presumably, will set the blade on fire. If a giant flaming knife just isn't enough for you, the pack will also include a special in-game shop with discounted items and a higher chance for rare items. Furthermore, the Survivor Pack includes a booster for both XP and stats.
Finally, those who pre-order from GAME will also get the Fashion Victim pack, which includes new skins for all playable characters. New skin is probably handy for those times when you find all of yours gnawed off by the undead.
We've contacted Deep Silver to find out if these bonuses are headed to North America as well. At the moment, US retailers are listing a pre-order special edition including a Steelbook case, weapon mods, character skins and a digital map. That's not to be confused with the $80 "Rigor Mortis" Edition.
Dead Island: Riptide launches April 23.
Update: Amazon now lists the same pre-order bonuses for the US as well.
