Sry if this has been posted before,but how about 'Capture The Package'(C.T.P.)?
Everyone spawns at the same time,and tryes too find a Hidden Package,which will spawn at a random location of the 100 Hidden Packages.
Another idea would be 'Package Ownage'(P.O.).
It would be a timed game with the 100 Hidden Packages,and there would be teams that would look for them.Once there was no time left,the team with most packages would win!
Would these be possible?
