The information was made public by Croteam, developers of Serious Sam
A lot of rumors have been going around the Internet about the potential launch date for the Steam Linux client, but nothing has been certain about the launch titles until now.Many game developers have announced their integration into Steam for Linux, and we found out about it from the CDR database.
The simple presence of a tile in the CDR database doesn't guarantee that the game will also be available at launch, just that it will arrive on the Valve's Linux platform sometime in the future.
Fortunately for us, some developers can't keep a secret and spilled the beans on the launch titles for Steam on Linux.
Croteam, the developers of the famous and extremely fun Serious Sam series, have made a casual announcement on Facebook.
“Linux version of Serious Sam 3: BFE will be included alongside Portal and Team Fortress 2 within the upcoming beta launch of Steam for Linux! More details will be revealed by Valve this week during Ubuntu Developer Summit (UDS),” stated the Facebook post.
Serious Sam 3: BFE is the latest in the series and features a new graphics engine and a new storyline. The game serves as a prequel to the original title, Serious Sam: The First Encounter.
Set against the collapsing temples of an ancient civilization and the crumbling cities of 22nd century Egypt, Serious Sam 3 is a combination of classic shooters and modern gameplay.
Portal, on the other hand, is a lot older and was first launched, for the Windows platform, in 2007 with the Orange Box (Half-Life 2, Episode One and Two, Team Fortress, and Portal).
It's an amazing puzzle first-person shooter, with a quirky storyline and great dialogue. It has also spawned a sequel, Portal 2, but there is now word on a Linux port for that one.
Team Fortress 2 is a multiplayer first-person shooter that pits two teams against one another, with various objectives.
CDR Database is a record of data that describes every Steam game and subscription provided by Valve for the Steam service. Usually, the new entries in the Steam database are firstly visible in the CDR Database before their official launch.
