Dead Island Dev Build Released on Steam by Mistake, Day 1 Patch Changelog

There's no press release out yet to my knowledge, but today Deep Silver and Techland's zombie FPS/RPG hybrid has been released in North America, although it appears it's not quite the smooth launch the publisher was planning as many players have reported various issues including, weirdly enough, the ability to activate noclip by pressing 'Y'. According to a Steam forums' users findings all of these issues may come down to one reason: the version of the game downloaded from Steam is actually a dev build instead of the official version, put online presumably by mistake, which obviously should never have been available to the public, especially since it apparently contains the verification code to authorize the game.

For all of those that have been scared by this report, there does appear to at least be some good news, as Destructoid reports that the title's day 1 patch will contain over 37 fixes:
'¢ Fixed map synchronization when player joins during map load.
'¢ Fixed saving player re-spawn position when playing in co-op mode.
'¢ Fixed occasional inability to complete sidequests in Laboratory.
'¢ Improved enemy awareness (zombies).
'¢ Fixed occasional bug with NPC's hands bend (IK)
'¢ Fixed spawning enemies in some quests after joining co-op game.
'¢ Fixed showing locations on invisible NPCs.
'¢ Fixed potential path blocker when quest "Knockin' on heaven's door" was completed before talking to Dominik during the "On the air" quest.
'¢ Fixed displaying gather rings near some doors.
'¢ Fixed enemy reaction to fire.
'¢ Fixed enemies' health and stamina bars in co-op.
'¢ Fixed filtering of games in lobby.
'¢ Volume of pickup's engine has been increased.
'¢ Fixed a number of issues causing game instability.
'¢ Fixed the switching of maps upon player death.
'¢ Fixed enemies unable to reach the player on some arenas.
'¢ Thrown items cannot be picked up by co-op players for five minutes.
'¢ Items from freshly opened containers cannot be picked up by other players for five seconds to prevent theft.
'¢ Fixed animation glitch when trading with team members.
'¢ More than one player can use a ladder at the same time.
'¢ Fixed stomping execution animation when target's attacked by a second player.
'¢ Fixed the infinite respawning of shooting enemies.
'¢ Fixed not hiding menu if players die inside a vehicle.
'¢ Fixed item level calculation when playing New Game Plus.
'¢ Added information about players requesting pause in co-op.
'¢ Fixed A.I. animation glitch after fast-traveling or using a map portal.
'¢ Added distinction between quest checkpoints and other types of saves.
'¢ Fixed bug causing all inventory to disappear.
'¢ Fixed reloading and kicking. After the clip goes in, the reload is a success.
'¢ Purna can gain bonus rage from both "Grim Inspiration" and "Inspiring Kick".
'¢ Only "Walker" type enemies increase the extra XP of the "Combo" skill from Xian's Survival skill tree.
'¢ Health regeneration is disabled during grabs.
'¢ Focus on items in shops not changing after selling or buying.
'¢ More HP for NPCs in escort missions.
'¢ Butcher enemies won't spawn at all during escort missions (hooray!)
'¢ Fixed tracking after loading checkpoint.
'¢ Increased minimum vertical distance to count a waypoint as passed for NPCs (they no longer wander back-and-forth).

One can hope any additional problem will be solved quickly.

Thanks, Rock, Paper, Shotgun.
