The best items are found in military outposts and special transports that land from time to time in random locations around the map. But these places are likely to feature a lot of other players, so be warned.

Interesting fact:

Respawn stated that, since they were restricted by their slightly outdated engine, they were hesitant to make Titanfall 3 next as the graphical fidelity wouldn’t be on par with the likes of CoD and Battlefield. Therefore, they came up with Apex as a last hurrah before moving on to a more advanced engine.
