Failing parkour in Co-op still forces a map restart.

Richard Jacket, WizardBath, and I managed to reach Round 30 before the game just faded and restarted, this actually happens frequently. I imagine this is similar to how in campaign Co-op getting run over by a tank would kill a player instantly and force a restart, but I really have no idea what really causes this.

Do we get the fifth place trophy?

As a former cod4 deathrun pro, if anyone is saying they hate to parkour cause its too hard, GIT GUD SCRUB!

This is Zombies Mode, not deathrun. People come to UGX and services similar to it for Zombies mode, not deathrun.

This is an awesome map, but the platforming is just absurd. The penalty is death, that's insane and unnecessary. If platforming is absolutely required than the penalty for failure should be losing a couple hundred points not outright dying. It takes forever to set up on this map, nothing is more frustrating than dying to platforming of all things in a Zombies map.

First off, I want to say that this map is absolutely amazing; custom character models, custom weapons, fantastic map design eight perks, even a new perk animation. I almost feel guilty for not paying money for this.

Anyways I have a few things I would like to say regarding the map's content. On occasion the box would just get bugged; it would become impossible to use it after a point, I've played the map nine separate times and three times this has happened to me, two out of those times it would occur after the box has teleported once. Also, I feel that the fire speed/bolt speed on the Kraber-AP Sniper is way to slow; I found that even with DoubleTap reloading the gun with Speed Cola after every shot was faster than waiting for the bolt animation to end.
