I have a new wonder weapon idea, this is powerful - but does not kill the zombies and has a massive con. Basically the ammo of the gun is 6/18, and this is meant as tactical gun, when you fire it it opens up a portal which lasts for the same as Gersch Device, the portal effect looks similar to that of the Anomalies from Primeval - cant be exactly the same but similar, zombies will be attracted to it and walk through it and disappear - but there not dead they've travelled in time - this is the con, the portal could potentially re-open any time in a future round and the zombies that went in before will come pouring out and this could screw you over if its in your training spot, it could re-open when you've got crawlers, or you may die before it re-opens.
I'm not sure how it would work if it were to lead to the past, that would be interesting, like a portal opens on round 1 but you dont get the gun till round 10, but you'd have to go back to that spot on round 10 or some point to fulfill the past and to make sure the portal opened in round 1, confusing concept but would be an interesting challenge, maybe if you dont shoot it at that spot within a certain time, the past gets altered and something could go wrong to one of the players, i.e perks/guns/points could be lost with the idea being you never got them in the first place in this altered timeline. But things could also change for the better - you could receive better guns, gain more points, gain a free perk. By fulfilling the past and shooting the gun, time would not change, you would not gain or lose anything. So you'd be gambling on yourself (and other players?) by not shooting the gun.
You may find this confusing and thats understandable but i thought this was such a cool idea and would be interesting to implement.
Wonder Weapon Name: The Time Portal or perhaps Parodox
