343 Industries has let players know that there’s still an Easter egg hunt on to find the remaining secrets in Halo 4’s Campaign.

Lead campaign designer Jesse Snyder writes:

“Did you find any secrets as you played through Campaign? Initially, fans found many things that they thought were Easter eggs. Discovering that, in fact, many were still hidden, we were relieved. Avid secret hunters claimed that some of our treasures would be found within days of launching the game. ‘Certainly, they’ll find them any day now,’ we thought. Time would prove both us the aforementioned secret hunters wrong.”

“Act quickly and maybe you’ll find an easter egg on your own, but that time is about to pass. We’ve decided to give you some hints to help you uncover our secrets, without telling you where they are outright. Additionally, we’ll be giving you more hints in future Bulletins. Knowing how well we’ve hidden our easter eggs, it only seems fair. Even though this may sound cliché, ‘If at first you don’t succeed, try, try, again.”

The clues can be found below.

Mission: Requiem

What is it?

An appreciation of architecture, and a return to nature.

Where is it?

It may be beautiful, but returning here is deadly.

Mission: Forerunner

What is it?

A deadly ambush waits for you

If you have the will to power through

Kill them all, your reward is great

Weapons to turn the tide of fate

Where is it?

After the enemies rain from the sky

Before the doorway through which you fly

You must return to the rock on which the ledge is by

Patience is a virtue, but your death is nigh

Mission: Midnight

What is it?

A congenial sight.

Where is it?

Lost in the belly of the beast.

So what are you waiting for? Get hunting!
