Shangri-La has many puzzles and traps, each one of them changes the game significantly, whether it is to your advantage or not. They include:
 * The many punji-stake traps which block you and the Zombies path, and the tricks you can use to avoid turning them on.
 * The Mine Cart is a difficult choice due to it's nature of putting you in the waterfall, which is a Zombie f*ckfest the Water Fall/Water Fountain trap
 * The Mud-Pit Maze has a random walkway system, which is different each time. Walking in the mud itself slows you down, so it's hard to avoid Zombies
 * The Zombie Monkies change your power-ups and chasing after them is a massive risk in order to obtain the power-up you want, which you may fail to get as you may miss them.
 * The Geysers can leave you sorrounded by Zombies as if they fall down them while you're trying to use one, it will stop and leave you for dead.
 * The random Perk-A-Cola positions can be very disappointing if you need to get them on the move.
 * The Napalm Zombie essentially blocks you from passing it, it's napalm patch also does this and Zombies are also effected by it, so choose where you kill the Napalm Zombie.
 * The Shrieker Zombie is always a priority due to the blinding effect.

And most of the puzzles are in the Eclipse Easter Egg. It is a bit Indiana Jones style, like having to match up all of the stepping stones, turning on the Eclipse and plugging the holes of the caverns with Spikemore spikes and using the Napalm Zombie to burn leaking gas.

"Five"s puzzles include the DEFCON system, and the elevators/teleporters.
