A few years back a Simple Shooting Gallery Game sample PKG for PS4 TestKit owners surfaced, and recently ThatGuyNamedJoey reported a curious PXG4: PS4 Full Game Standard Disc Game Test 4 (Prod) listing for Whale Whale Whale: What Do We Have Here? (80.22 MB) by WILD SWANS on PlayStation Store (Cached Page) at $0.49 that appears to be a Sony marketing tool used for early server development and integration testing with PS4 / PS5 titles based on the description.
Needless to say, the mysterious application has since been removed leaving only an “Unable to Find This Page: It may be unavailable or the address may be incorrect. Select [Home] to continue browsing the PlayStation Store.” default error template in its place.
However, before it was taken down YaboyPS5 (aka Minecraft, FNAF, AndMore on YouTube) had the foresight to capture a demo video of it in action below! (PS4_and_PS5_store.mp4 – 82.93 MB mirror in case $ony removes the YouTube demo)
PS4 and PS5 store????
I found this on the PlayStation store on August 24 2020 its called “PXG4: PS4 Full Game Standard Disk Game Test 4 (Prod)”
If anyone knows more about this odd and short-lived PlayStation Store title feel free to share further details in the comments below.
