As you make your way through the Story Mode, you’ll soon find out that the final levels of every chapter are locked with not one but three keys. If you’ve scoured every level prior by now, you’re probably wondering where in the heck you’ll find the missing keys. There aren’t any collectibles hidden in the levels, after all, so where could they be?

How to Unlock the Chapter Finale in Into the Dead 2

Well, as it turns out, the keys are hiding in plain sight. In addition to the usual requirement of beating every level leading up to the finale, you must also complete all of the chapters’ side objectives in order to unlock it. They’re the objectives that appear on the top-right side of the screen on the level select page.

Chances are, there’s no way you’ll manage to knock out all of the side objectives on your first sprint through the chapter. In fact, I highly suggest focusing on surviving your first run rather than risking your life for the side objectives.

If you at least get through the chapter, you can then go back and replay levels to complete the side objectives. Replaying a level you’ve already beaten costs only a third of the stamina required to play it the first time, which means you’re risking far less as you put your life on the line to complete side objectives.

Once you finish up with all of the chapter’s side objectives, the final level unlocks. Beating it rewards you with new weapon blueprints and some weapon parts before it ushers you on to the next chapter where you get to repeat the process all over again with more difficult side objectives.
