Open in Youtube to see time stamps for all achievements.It’s the 10th annual award ceremony for the Puzzling StackExchange community! As the host and his attendants are handing out the awards to the best members of the community, they suddenly realize that they have forgotten who the recipient of the Great Puzzling Trophy was! Otherwise, you're wasting time on very simple platforming areas. The majority of the game is very straightforward, so I don't recommend watching the video except for referring to birds or artifacts as needed, or if you get stuck. The following video shows a full walkthrough of the game, including all birds and all artifacts. If you miss any, you can go back with chapter select to grab them, but then you must replay the last chapter and reach the end of the game with all four artifacts to unlock this achievement. When you pause the game you'll be able to see outlines of the four artifacts across the middle of the screen, and when you collect them they'll be colored in. These are linear platforming areas, and getting to the end will reward you with an artifact. Then, you'll need to head right and drop down and under the platform you were on, and press on the dimensional tear to go to a low gravity dimension. Each artifact is obtained by first coming to a large obelisk in the background (which are very obvious and tough to miss) and solving a simple puzzle to activate the hologram. To unlock this achievement, you must reach the end of the game after having obtained all four artifacts. The gameplay is pretty simple and basic - you'll spend the majority of the game running right and jumping - and the stealth bits are really easy, but it's a short and enjoyable game for sure, as well as offering some very easy gamerscore. Planet Alpha is a fun side scrolling game with beautiful graphics and environments to see as you progress through the planet. Once you've gotten all birds and artifacts in one playthrough (not one sitting), you'll have wrapped up this completion. I highly recommend referencing this video as you go just to avoid having to replay anything. There are also time stamps for each collectible, in case you prefer to play on your own and just make sure you don't miss a collectible. The " Timeline Erased" achievement solution contains a video showing the full game from start to finish with all birds and all artifacts being collected. You'll also need to collect all four and then finish the game with all four collected to unlock " Timeline Erased" but if you miss one you can go back with chapter select and get it, then reach the end of the game again. When you pause the game you can see the outline of the four artifacts, and they will appear colored on the pause menu once you collect them.


The artifacts, on the other hand, don't seem to be an issue. I highly recommend checking the guide for each bird as you go so you don't miss one, otherwise you risk having to replay the game. While there is chapter select, completing the game and then going back and collecting any missing birds doesn't seem to unlock " All Together" for people. One important thing to be aware of is that collecting all of the birds must be done in a single playthrough. They are all for collecting two types of collectibles: birds, which are hidden in various places, and then artifacts, which are obtained by solving simple puzzles to open up an alternate dimension, where you can find an artifact at the end. There are no progress or story achievements, and no miscellaneous achievements. Every achievement is related to collectibles, so make sure to grab them all as you go and this will be a very quick and easy completion. You'll also be using a simple mechanic of switching between day and night to make different plants appear to help you progress. The game mainly consists of running and jumping, with a bit of sneaking, to get through each area. You come to as a traveler on a strange planet, trying to find your way through it, all the while being attacked by denizens and security bots. Planet Alpha is a side scrolling platformer with some very basic stealth and action elements to it. Unobtainable/glitched achievements: None
