Tom Clancy's Rainbow Six Siege [official site] was due to abseil through windows, smash through doors, and blow up ceilings on October 13th, but it's better to be safe than sorry with such showy plans. After reviewing feedback the game's had from playtesting, the closed alpha, showings at shows, and so on, Ubisoft have decided it's not quite ready for release and have delayed it.
Rainbow Siege Siege is now due on December 1st.
Ubisoft explain in the blog post announcing this delay:
"This wasn't an easy decision, but based on the feedback we've received, and based on our own internal tests, we felt there are adjustments and improvements we can make, including improving the co-op experience across all game modes, weapon and gadget balancing, as well as menu and interface navigation. We're taking a little more time to make these changes, and we think it's the right call."
If you're planning to give the closed beta a go - signups are over here (I trust you wouldn't pre-order for beta access, especially given how Ubi scrapped Anno 2205's promised beta) - then rest assured that it's still going ahead on September 24th.
Here's what Pip and Graham made of their short time with the closed alpha version. If you've had a bash yourself, what did you think?
