One of the hardest parts of Metal Gear Solid Delta: Snake Eater is hitting all the Ga-ko and Kerotan dolls during the bike chase sequence. This video guide should help you find the locations for these collectibles.
Before watching the video, it is important to note that you should create a manual save file at the start of the chase. This is because the game will auto save every time you enter a new area. So, if you miss out on a Ga-ko and Kerotan, then you can reload the manual save to return to the same location quickly.
Furthermore, you only have to hit the Ga-ko and Kerotan once to have it registered as an unlock. This means that you can hit one collectible, reload, and don’t have to hit it again; instead, you can focus on hitting the second one in the area.
Once you hit both collectibles in the area, you can move onto the next one. Create a separate manual save for every area you enter since it is likely you need to reload often.
