Watch and enjoy the opening cutscene as it is your first experience with the geniousness of Psychonauts then drop back here with me.
The game now asks you to "Create a Profile" aka pick a bunk. This is basically you creating your save file, so enter in your nickname of choice and another scene will occur.
After that a little tutorial of sorts will occur. A man by the name of Ford Cruller will appear (although you won't know thats his name until later on) and he will make you look right and up at two different items. One is called a Psi Challenge Marker and the other is Psi Challenge Marker piece, from a broken Marker. He'll explain to you about putting the broken ones back together with Psi Cores. Check the items section if you need a recap.
When the game kicks back in all the kids will run off to "Basic Braining" and they tell you not to be late! At this point you are left free to roam around.
If you don't want to search around the camp and you want to go straight to the Basic Braining then skip over this little section. But within this section note we will complete the first Psi-Challenge Marker and gather a decent amount of arrowheads, along with trying out some of Raz's platforming abilities. Your choice though.
So lets roam around camp a bit first. If you head around the right side of the cabin you came out of (right when facing the door) there is a piece of a Psi-Card. Behind the house you'll find an arrowhead buried undergound, press Y to dig it up. See the items section for details on this item. When you get around to the other side of your cabin a short scene will occur, nothing of utmost importance, just for fun.
Follow along the fence and you'll find another arrowhead in the ground. If you keep going you'll run into Ford Cruller again and he'll tell you that the rest of camp is off limits until after Basic Braining. There's a kid wearing a funny hat sitting not to much further away, he's bear hunting if you will, humerous to talk to. A bit past him there are a bunch of tree trunks sticking out of the ground and if you jump on them you can grind a bit, on top of one of them is another Psi-Card. Explore around these tree trunks a bit to find a few more arrowheads.
Just to note, I'm not going to hold your hand through getting arrowheads anymore because for all I know they may show up at random and they are everywhere. So, keep your eyes out and grab them when you can. I'll let you know when I have enough to buy things and you should be around the same amount as me if you are exploring as I am.
Walking back towards your cabin there are two kids sitting on the ground talking about the "worst band name ever," next to the house right there is another arrowhead. You can talk to them if you want to hear about a story from last years Basic Braining.
Standing at the two kids and facing the tree trunk we just hung around look slightly to the left and there's a bridge that goes up the tree, underneath it is another Psi-Card. Don't go up the bridge quite yet, instead keep going away from the cabin we were just at to a speaker pole near another camper. Climb up this pole and on the top you'll receive yet another Psi- Card. Move closer to this kid for a humorous scene.
There is a cabin next to the kid with a Net (see Items section) by it that you can use to get on top of the cabin. Double jump to get up on the net then do a sweet jump on to the roof of the cabin for another Psi-Card. Walk straight across the roof of the cabin and there is a tight rope that you can walk across to another cabin with yet another Psi-Card!
Now straight across that roof there are some poles (items section of course) jump up and grab onto the first one and then swing to the second one, now straight in front of you is a wall covered in netting that you can swing and jump onto. Climb up to the top and then hold left and double jump off to reach the next area up here for another card!
Straight back here is a cave that you can slide down, at the bottom is a safe that is "frozen solid" so we'll have to return to that later. On the wall is a net that you can climb part way back up and exit out the side. Go down this side to receive another Psi-Card. 1 more to our first complete Marker! And head up the hall to the lucky number 9! Also, a ladder to climb up.
You'll come out a well in the middle of the camp that you may have ran by earlier, and its now time to take on Basic Braining! So head up that bridge by where we picked up some Psi-Cards before and at the top you'll get a short scene with some more campers. One of which will give you your Smelling Salts (see items section!) Feel free to talk to all the campers, but your main goal is to talk to Oleander when your ready to start Basic Braining.
