Alien team: One.
You got this granger, right?, and it screws things up. By screwing the bulb up, it gets deconstructed, then, it reconstructs it so finally, the bulb is changed.
You mave have some dretches and tyrants running around hunting down humans to keep the granger save during the changing of the bulb, but that's the only interference from the teammates.
Human team: ... well, that's a bit more sophisticated.
First, you have this noob camper, right? He gets killed thirteen times, then he shots a dretch by accident and gets enough money to buy a shotgun. With this gun, he will stand in the way waiting for another dretch crossing his path, feeling like the terminator himself. Because the camper is unaware of the fact that aliens can sense humans and know who is standing there, they won't. Eventually a dragoon will chomp him down.
Nonetheless, this camper is standing in the way. Another noob will realize the troubles within the base and will deconstruct the whole base to be able to place it somewhere else to change the lightbulb on a much better place where you can see approaching aliens from all sides - which also means that aliens can spot it as well and it is nearly impossible to defend, but who cares? Unfortunately, this doesn't work out because the builder is being bitten by some dretches.
The lightbulb doesn't get changed, alien team wins.
