Note: When editing an existing map that has no MyLevel built in, always make sure to save the map to a backup filename in case you screwup adding that... because I frequently don't and occasionally mess that up, which is why I had to start from scratch on this map.

What we have here is a BIG map of very long corridors and a central medium-sized arena area.

Original mapper, for some crazy reason, put 2 flags on each team at the end of each long corridor (probably explains the map name) but that seemed ridiculous so I put an end to that. Now down 1 corridor is a flag and down the other is a tank.

Map never had a lot of weapons, originally only the shock rifle & minigun & flak cannon. Due to the XV, from that cache of weapons (that make it a fair fight between those in vehicles and those not) I found on another map, replaced the shock rifle with the explosive crossbow. Also placed a redeemer in the central area and 2 megahealths for each team.

Just above each flag is a ut2k4 cannon, which makes things interesting. Cannons apparently do not register XV but as you have to get out of the tank to pick up the flag, that's when the cannon locks onto you... and will stay locked on even after you get back in the tank.

So long as you're still in range, anyway.

Now, I only placed 1 tank with each team, but don't feel like that is so limiting.

I noticed the vehicle factories in XV have the option to spawn additional vehicles as soon as the initial one moves away from its start point. Potentially everyone on your team can get their own tank, if they like.
