I only recently started doing some speedruns of Creep world 4 with a friend and we are wondering if getting the easter egg in Farside should be needed for the 100% run?

The main argument for including the easter egg is that is is a part of the map and has its own steam achievement. However, the easter egg is completely unnecessary to complete the map and is not an objective.

The same would go for the easter egg in 'before time'.

We're thinking of doing a 110% category for easter egg levels - stay tuned! The plan will be that 100% runs are just completing all listed objectives.
