They've got the right idea. Ranged weapons in such an enclosed area is bound to be counter-productive, especially when you stand just as much chance as hitting a team-mate as you do a robot.

As if self-replicating killer robots weren't enough, several compartments on the robots' "bodies" slide open and eight metallic tentacles emerge, each topped with a weapon. Saws, drills, massive spear-like needles, spiked clubs, and beam weapons topped with angry looking bayonets are just part of the deadly arsenal they now have to contend with.
