First of all, thanks to everyone for the support and feedback. It's all really useful and we're all amazed about how much this has blown up. We even made it briefly to #1 on ModDB, which we never imagined would happen.
Anyway, we discussed in our first blog post that we were trying to decide if we should stick to hl1 or hl2 style graphics. We still can't decide, so we've made a poll so we can gauge what most people want, and we'll try to adhere to the most popular option. You can take the poll here. Please be honest, as we'll be basing most of the mod on this info.
Also since releasing the demo, we've gotten a lot more people on the team, and we now consist of almost 10 people. We can't express how thankful we are, and remember if you want to join now you still can.
