If you’ve been looking to pick up Valve’s famous puzzle-solving game, the two Portal games are on sale again this weekend on Steam. It’s not the first time we’ve seen this sale, but for over the past year, Valve’s Portal promotions have always taken 75% off every time. So short of them giving away the game for free, it’s safe to assume these sale prices are the lowest they’ll go.
Up till April 22, you can pick up a single copy of Portal 2 for $4.99 (normally $19.99) or two copies to send one to a friend for a total of $8.74 (normally $34.98). Valve is also offering a Portal Bundle which gives you both the original Portal and Portal 2 for $6.24 (normally $24.98).
The original Portal made its debut in 2007, which then spawned a sequel that is Portal 2 in 2011. Both games work on Windows and Mac, and a single purchase gives you download access to game versions for both platforms.
