And more.

When will Intrusion be released?

Intrusion is nowhere near completed, the release date cannot be pinned down yet.

How long is Intrusion?

Intrusion is too early in development to pin down the length. However, we're aiming for several hours of play time. (This may wildly vary between the skills of different players.)

Do I need Portal 2 to play?

Yes, Intrusion runs on Portal 2: Community Edition, which requires that you own Portal 2 to play. You will not need either Portal 2, or Community Edition installed to play. You will only need to own Portal 2.

Will the soundtrack be released?
