K NOW THYSELF
This heavily-armoured beast is you. Well, it could be. There are plenty of skins already, and while the fanciest cost money, you can get some decent ones for free from the drops you unlock.
Your trusty portal gun. Again, there are different skins to unlock for it, but to be honest it’s hard to tell them apart outside your menus. The important thing is that it lets you shoot those tasty portals!
Did we mention that you have a jetpack? Fuel’s very limited, but it’s handy for extended jumps and controlled descents. And, yes, there are different colours and designs to be had. We do love jetpacks.
