Vampirism appears to be a small team vs big team sort of map. Vampires versus Humans. There are only two vampires, and 6 humans so it’s clear the vampires have more HP and buffs then the humans do.

The objective of the game depends on which team you are on:
If you’re a vampire, it is to hunt down the humans and kill them. When you kill a human you render them a vampire.

If you’re a human, it is to band together with the humans, mine, build fortifications from the vampires, and if possible, kill the vampires.

The game can go many ways, and there are a lot of different spots on the map for humans to go and set up their base.

But be careful, when a vampire is persistant they can still break through your fortifications.

It’s a good idea to build lots of towers, and destructible rocks to slow the vampires down and inflict max DPS.

Vampires: It’s a good idea to save your Vespene gas so you can buy items from the shop near your spawn.

Once you die as a vampire, it’s game over. You can opt to stay and watch the game.

Once you die as a human, it’s too another vampire, so you get to be a vampire. If you die here, well, you know.

Overall, this was a pretty interesting custom map. Definitely fun to waste time with.
