Well guess how most games in high rounds on virtually every zombies game end? Because of the reset, or your so called "game freezing". High rounds in zombies are about speed, because the game will always eventually reset. Its about how many rounds you can cramp into the given time. Its the same on every map from WAW to Bo3, its about cramping the most amount of rounds into the reset time given. Just for example, whilst Cruppz's Shi No Numa Game has 10000 rounds, its done in roughly 92 hours and was very close to reseting before said goal. I am assuming you are quite inexperienced with how very high round games go, and its obvious from your post above.
