How do you find out on blk ops when first strike map pack comes for ps3?

Unfortunately, I can't give you a specific date for when the "First Strike" map pack for Black Ops on PS3 will be released. Here's why:

* That information is no longer relevant: The "First Strike" map pack for Black Ops was released in 2011. The PS3 has been discontinued, and the online servers for Black Ops are likely shut down.

* I am an AI, not a time traveler: I don't have access to past events or release schedules.

However, if you're interested in playing Call of Duty: Black Ops, you can find more information about the game on the official Call of Duty website or other gaming websites.

Let me know if you have any other questions about Call of Duty or video games!
