SC4.0b has been out for a few months now... I hope everyone's gave it a fair chance on some non-xp mod servers :P The updated Incoming was included in the release, including a hidden fish. If you haven't found him yet go and try, you can find him by doing something silly somewhere in the spawn/weapons/HQ area.
Work on Incoming 2 has resumed, although at a rather slow rate 'cos I suck. Should be epic once it's done though, might take a while! Everyone on the SC team seems to be taking a little break, since certain members have other issues to attend to, but the patch should be out within the next couple of months.
