Users who are having difficulties playing Umbrella Corps’ online or single-player The Experiment modes on PS4 aren’t aware they’ve not yet fully downloaded the game.

Umbrella Corps comes as two installation files — one 3.7GB core download, plus another 4.8GB download for application data. That latter download has the files needed to play anything outside of the game’s tutorial.

To check the progress of the second download, head to Notifications > Downloads, as shown below:

Enjoy!
