Here's some pictures to show you guys. The battle was, as Speedway Master told me, epic. Besides that, there was an enormous amount of lag. I don't know about you guys, but even on my incredibly low amount of lag, I was having a hard doing anything. I was literally throwing out random clicks to see if I would get lucky and hit an enemy or too.
No dice.
I mean, I'm sure if these invasions are permanent the lag will die down because people will stop doing them so often. But until then, this lag is horrible. I don't think I'll do any invasions if it means having over a hundred players on the map and two hundred enemies.
P.S. Does the amount of players during an invasion determain the amount of enemies? Also, I don't know if I got a shot or not, but when I saw Jolly Roger his enemy level was 77.
The amount of fog is cool. I love how that at a certain distance you can't see enemies. This makes the invasion even more "creepy" and "hard". It adds to the effect is basically what I'm trying to say.

Jolly Roger running back and forth attacking us. He didn't move much besides walking and waving his hands back and forth. I would like to see him use his pistol. And the black circle is a pretty great attack. I was one of many that died because of it.

I felt sorry for this guy. Because of the lag he was too busy trying to aim, but instead this poor guy got knocked out right after me.
EDIT: Actually, now seeing some pictures I've noticed the level is actually ??. At first I thought it was 77, but when I got a closer look I saw it was two question marks. Strange.
