Good gameplay, good guns but things to add:

- Playing in Coop to finish the map is so hard since 1 min to use the TP for all players, which means, 4 minutes to teleport each person.
- Zombies and Panzers get stuck in the other Arena when you teleport
- End game should be paid without requiring all players as long as you fix the minute requirement for the whole team and make it separate for each player.

Other than that, good challenge
