Sad news from Robot Entertainment: Orcs Must Die! Unchained is shutting down due to operating at a financial loss. The studio is still going but this and two PC titles will be shutting down permanently.
Here's an excerpt from the studio's statement:
"We've kept these games operating at a financial loss for many months. Unfortunately, it's no longer sustainable for us to do so. We must shift our focus to future games and make our investments there.Our eagle-eyed Game Information team have noted that the game is already delisted in the EU PlayStation Store. It's still available in the NA Store at the time of writing.
All three games will remain playable until Monday, April 8th, 2019 at 10:00 a.m. Central Time (UTC-05:00). Commencing immediately, all players logging into Orcs Must Die! Unchained and Hero Academy 2 will receive a substantial free grant of hard and soft currencies to enjoy the remaining weeks of live play. You may have to wait up to 24 hours for the currency grant to arrive in your account. We do not have a way to immediately make the grants upon first login."
If you're halfway through your trophy list, make sure to get unlocking before the game shuts down entirely on April 8th.
