Invasion could be potential a fun game mode but the execution is just poorly done. It's a cluttered mess, no minimap and it takes long from going to point A to B. Sure, you can see on the lines when you complete a section. But still, sometimes it's bugged and just put's you in a endless loop.
This contributes in knowing when you completed it 100% or not. It's just a cluttered mess, also the camera angle sometimes is just awful. You can't also look further ahead. On my 4k screen, everything is sharp but on my 1080p, I got insane depth of field effect while walking on the Invasion map.
Don't get me started on the overused modifiers.
