Can you switch between upgrades or do you have to pick one and stick with it?Which one is the best all around?Thanks.

you can replace them. but you have to go back and forth to the jukebox in the sink.

Get the jukebox personality module or whatever its called and any upgrades you find in the DLC can be installed into the Jukebox. You can then switch them at any time using the Jukebox.

I personally like robo-scorpion and tarantula. They are the only two that actually deal good damage.

Thanks guys.The tarantula looks the best to me(I'm a closet pyromaniac) but I wasn't sure if I could change it later if I wanted to.

Other than opening force fields I never even used that damn thing. such a waste of an invintory slot.

At least it doesn't weigh alot.I find myself using the Gauss YCS most of the time or my Sequoia.
