We hadn't played the Underground map for a long time so we decided to revisit it. This time we managed to reach wave 94.
For us the tunnel in Underground is pretty much the key to reaching higher waves. Our strategy makes use of the tunnel for both juggernaut and non-juggernaut waves. The only difference is which part of the tunnel we defend for juggernaut and non-juggernaut waves.
Note: We use grenade sentries up to about wave 50, then normal sentries after that. At higher waves the enemies it's hard to kill all of the enemies before they get close and grenade sentries start doing damage to you. Normal sentries also give a much clearer view of targets, which you need at high waves as you have to start hitting them as far off as possible.
This map is also one of the easiest to run laps on during juggernaut waves.
Our next vid will show a strategy for making high waves (70+) on the tier 2 map Mission.

Thanks Axstar100, still trying to meet up to have that game you wanted to play. Timezone differences are a pain!
