Two popular Valve games, Portal and Portal 2, have arrived on Steam for Linux. The two games, released in 2007 and 2011 respectively, have previously been available for the Windows and Mac platforms.
This latest Valve game release for Linux is very good news at a time when Steam for Linux usage has been sinking. The April figures for the Steam hardware survey are now public and they indicate further losses. In March the Linux usage was at 1.6-1.7% and now, for April, it’s down to 1.5-1.6%.
Portal is selling for $9.99, while the newer Portal 2 retails for $19.99. The Portal series is a very popular first-person puzzle-platform game. Other big releases such as Left 4 Dead 2 are expected to be coming soon.
