How so?
The maps has a ton of issues present that could be put down to the limitations of the engine and the size of the map in question, though some could be down to bad programming, I am not 100% on the reasons but either way the map is very broken.
Parts glitch out and cannot be picked up, Staffs disappearing out of the game completely, Panzers spawning in and locking the game down completely, invicible panzers, zombies derping out, giants kicking players out of the map completely, Tank killing players on 3 bars or less (I know that one is a death barrier put in due to stinky, smelly glitchers), zombies randomly derping out around the map.
There is more too. Dying on a solo game while walking around with a shield in front of you because you clipped some random death barrier poking out of a tank path or stairwell, zombies running through charged staff shots and refusing to die, staff shots not firing as they should, graphical and sound glitches in abundances, fire staff causing the game to crash after round 60, air strikes and monkey bombs not working in certain areas of the map, tank killing players at the top of the church when pulling in after a journey from tank station, elemental punches not working despite making contact...
There is even more issues but they are the main ones I can think of off the top of my head. I know the majority could be down to programming, I'm not sure but the sheer size of the map would suggest the errors are more present on this particular map due to it maybe hitting limitations though I am cannot say for sure seeing as I am not overly familiar with Radiant outside of the basics.
I play a lot of Origins though... pretty much daily to be honest and if you play the map a lot you will see these issues frequently and it definitely makes it the most broken map to date.
