Saying that we have "updated" the AI is misleading. There was no point where we had all the original AI and simply upgraded it here and there; we studied, reverse-engineered, and completely re-wrote the AI. We've done so using the AI framework of the Source Engine, so our new AI will take complete advantage of everything the Source AI brought to the table, but when it comes to specific AI behaviour it's all been completely re-written.
