1) At the base in the start of the level, find some crates and stack them to the left of the base's door. On the top is a Treasure Chest.

1) From the starting point, go up to the first potted bush you see, then walk right along the concrete walkway until you see a garage door on your right. Walk up to it, and it will open, revealing a room with a TV a soccer/football ball and net, a pinball machine, a poker table, a vending machine and a banner. Go into it to register the secret and spawn a few Primitives outside. Kicking the soccer ball into the goal net will reveal a Super Health.

2) In the jumping pad portion of the level, get on the first pad and look behind you. You'll see several Treasure Bags in a tight space. Position yourself so that you land in that space, and a secret will be registered. The best way to get to it is to try to reach it while you're going up, not down. There are nine treasure bags in total.

3) On the pad where you find a XM-214-A Minigun, CH-181 Hover Bike and two red ScorpSoldiers, go to the left. You'll see a tree with carrots on it. Walk next to it to register the secret. If you shoot the carrots, each one will spawn in an Extra Small Health.

1) In the first grassy field past the sloped walkway, there is a strange machine and a dead bunny near the back wall. You'll need to stack some crates so that you can you can toss the bunny in the rectangular opening and reach the Serious Bomb on the device. These crates can be found on the upper right corner. Once the bunny has been put in the machine, a secret will register and a ragdoll bunny sausage will come out of the machine, which you can mess around with.

-
2) Past the crates, you will be in a huge arena with garages on your right. Look left until you see another machine sticking up with a red switch on it. Walk over to it and use it. Another crane will move and drop off both an Extra Large Armor and a Super Health. Pressing the switch will register the secret.
