The Bulkwalk is a Tower Defense game.... kinda. The object is for the attackers to walk through the front door of the fort, and for the defense to stop them. Each game has two rounds, a round for each team, and each round is 5 minutes. After 3 minutes, it becomes a night battle and while its not completely dark, it becomes much harder to see the attackers advancing up the field. The defenders must toss flares to light the sky so they can see their targets better.

All the attackers start and spawn at their camp, on the far side of the field. If they make it to the village (mid-field), then they can activate the teleport reciever there by blowing up the fusion coil that is blocking it. This will allow them a little quicker travels, as the map is a pretty long run. There is basically 3 paths that the attackers can take. The left and right sides offer plenty of protection. The center is the most dangerous, but has some decent items along the way.

The defenders have 3 areas of interest. One man will start the game in the skybubble, where he will have a misslepod and fire grenades to rain hell to those below. If he dies, commits suicide, there is no respawn up there, so theres only one eye in the sky. The defenders also control the bunker (at the start of the game). Two men will start at the bunker, and should move quickly to work that turret. There is no defender respawns at the bunker (mid-field). Lastly there is the fort. The remainder of the defenders will spawn here, and all the defender respawns are in or around the fort. At the fort there is flares, fire grenades, a turret, a missle pod and one sniper.

Looking up field. The fort is so far away it doesn't even fully appear.

Why flares are needed!

Nighttime WITHOUT a flare!

*The nighttime is actually quite a bit darker than this during game play.
