Portal 2 turned 10 this week and gave us the perfect excuse to return to its timeless (and arguably unmatched) puzzle-platform gameplay. But for those who know the levels of the game like the back of their companion cubes, check out the recently released free mod. Portal reloadedthat adds a whole new time travel mechanic to master. It includes 25 levels aimed at Portal 2 veterans, full English voice overs, and subtitle support for 11 languages.

We played through the first levels of Portal Reloaded and it might as well be a full-fledged sequel. The opening puzzles introduce you to the time travel mechanics and should introduce you back to the headspace portal puzzle solving games that are required if it’s been a few years since you last played.

You will receive the legendary portal weapon shortly after the intro. You’ll solve a few more puzzles with pre-placed time warps in the levels, then your portal weapon unlocks the ability to shoot green portals that you can use to hop between game periods at your own discretion. From then on the puzzles are an absolute insane.

As Portal Reloaded’s unnamed AI companion explained early on, adding time to the mix forces you to “think in four dimensions” and “not just where to place portals, but when”. The additional dimension also has its own rules. Some are obvious – moving an object in the present will affect its location in the future – while others take more getting used to, e.g. B. how objects from the future can be brought into the present, but not the other way around. These new rules add an extra layer of complexity that is likely to challenge even the most seasoned Portal 2 players.

I got away from my brief hands-on time with Portal Reloaded and was excited to play more. The new time travel mechanic, puzzle design, and overall production values ​​of the mod are close to those of Valve – but it’s definitely made for portal experts.

(Fortunately, the developers made one official walkthrough You can use if you get stumped.) You can Download Portal Reloaded for free on Steam If you already have a copy of Portal 2. The mod will run on any PC that Portal 2 can run on.
