I uninstalled zypper in openSuse Tumbleweed by accident, how do I get it back?

I thought I'd do some cleaning up, so I ran:

zypper packages --orphaned | awk -F'|' 'NR==0 || NR==1 || NR==2 || NR==3 || NR==4 {next} {print $3}' \
    | grep -v Name | sudo xargs zypper remove --clean-deps

And somehow zypper itself was one of the packages that got removed. So now zypper is missing, how do I go about getting it back?
