Valve-Approved Sequel To Half-Life: Opposing Force Will Be Sold On Steam
 

Now to wait for the fan-made, Valve-approved Half-Life 3 that they are too lazy to make themselves. Prospekt is a mod that functions as as sequel to Opposing Force, letting you play as Adrian Shepard, the soldier you played in Opposing Force, during the events of Half-Life 2. These sorts of things are not usually a big deal. Mods are everywhere, mod-sequels have been churned out for ages, especially for Half-Life. Except that the key difference here is this one has received "official Valve approval for Half-life 2 license and assets" and will go on sale on Steam for $9.99 sometime next month.
