Easy there, partner.
I estimate I'm about one week away from finishing architecture on the detention center revamp. Once this is completed, we'll be ready to move onto enemies and test building for the next release of the mod. That release will include the new detention center and ramses hed. I'll upload some new screenshots once the architecture work is finished.
From this, I gather that the Detention Center level is nearly a week away from completion, not the whole demo itself. After that week is over (or however long it takes them to complete the Detention Center architecture), they will then be one step closer to releasing the demo.
To the team: That entry is dated 7.8.2009. Does this go by the European (day-month-year) or American (month-day-year) method of dating? I confess that I have no been paying attention to the main page, so this entry is either two months old or was posted today.
