Fortnite Season 5 is just around the corner, and Epic has been steadily hinting at a historical or time travel theme this time around. Those clues are slowly getting more explicit, and the latest teaser image appears to be at it again--perhaps even showing an upcoming piece of equipment in the process.

The teaser image dropped on Twitter shows a stylized axe similar to Viking and Scandinavian hatchets. We can probably expect to see the axe make an appearance in Fortnite proper, perhaps as part of the Season 5 Battle Pass, which should be full of new cosmetic rewards. The same image appeared in today's in-game updates menu, with the phrase "Worlds Collide." That would seem to tie in with everything we've seen happening in the past few weeks.
