Immortal Planet Cheats and Tips

When you start Immortal Planet you will be given the choice between the Assault Blade, Shieldaxe, and Swordspear. There are though several other weapons you can pick up as you progress through the game which will make help you complete the game. Listed below are these weapons and how you obtain them.

Gunaxe
In Fortress area: Find and talk to the man watching the paintings and then kill him.

Splitspear
Head south after killing the temple area boss. You will find a merchant selling the spear.

Cryo Saber
Head towards the archives area. Near the platform you will find it's owner. Talk to him and kill him after.

Fireblade
Near the frozen archivist you will find a hole. Jump into it and at the north-west corner you will pick up the blade.

Wingrazor
Talk to the man at the prison and then kill him.

To get the Ultimate Challenge achievement/trophy you need to complete the ultimate challenge. You will find the ultimate challenge by the cryopod in the forbidden temple area, but before you can access it you will need to defeat a hostile NPC in each main area of the game. This means defeating 3 NPCs and upon defeating each of them you will be awarded a weapon.

Once you have defeated all 3 NPC's you will be able to access the ultimate challenge which tasks you with defeating all three of the NPCs at once. Focus your attention on defeating one of the NPCs because once one is down the fight becomes considerably easier.

To get the Silent Assassin achievement/trophy you must complete the first room without taking any damage. This means killing the two enemies that are there, this can be made easier once you have unlocked the shortcut back to your crypod from the left side of the room. This will enable you to kill the first enemy quickly by ambushing him as he will be facing away from the shortcut you unlocked. This basically means you then only have to deal with one of the enemies. It is important to remember that blocking will void the achievement/trophy, you can though dodge.

You will encounter the final boss in Immortal Planet once you have defeated each area boss twice in each of the three zones and dropped down the hole near the frozen NPC. The boss wields a large hammer, has seeker orbs and is able to spawn two clones of himself. These clones can be taken down with one hit, but he will replace them almost instantly. Once the boss has had his health go down to roughly half he will fully heal, he will do this twice. The third time he will no longer heal and can be defeated. The best strategy for taking this boss down is to use the throwing knife or the Wingrazor weapon they will enable you to keep your distance from his clones.

To get the Bad Ending achievement/trophy you must finish the game. In order to do this you need to defeat each area boss twice in each of the three zones (Prison, Fortress, and Archives). When you have met this requirement you will be able to face the final boss of Immortal Planet by dropping down the hole in the floor near the frozen NPC. Once you have defeated the boss you will be able to interact with the two panels and sit in the escape chair which will unlock the Bad Ending Achievement/Trophy.
