I haven't been able to configure the AI to carry knives. I did try to do so but the editor doesn't support the feature but, yeah, it would be cool to have some of the guys charge at the Player with knives. I would have liked some of the staff in the medlab to hack at the Player with scalpels - that would be cool, too, but not with the current build.
So sorry, no. No knives allowed - someone might get hurt.
Expect pistols, sure - but none of these make an appearance in the map: Pulse Rifles, Smartguns, Grenade Launchers or other Marine associated gear. As this map takes place BEFORE the marines arrive at the decimated colony and the civilian colonists don't have that kind of gear to hold their own against the Alien surprise attack, you won't have to face them.
Expect the early stage of the map to be a tasty smorgasbord of head chomping until the colonists organise their desperate defence and start handing out firearms to the survivors.
Go check out the screenshots in the link on the first page. You'll see some weapons in use. Umm... I think.
