This map is inspired by the Batman: Arkham Asylum DLC 'Hothouse Prey'. In it, one of your party will play as the Batman and the others as the Joker's henchmen. The gameplay is designed to mimic that of the predator challenges in the game, featuring secret passages (tunnels), gargoyles (obelisks) and equipment such as grav lifts, flares and power drains to help batman achieve his goal. That goal is to take out the armed henchman intending to snap his neck.

Since the henchmen have guns, the direct approach is suicide. You have to use stealth, markers above the henchmen's heads and the equipment provided to take them all out. As the Batman you will start with a plasma pistol which, when fully charged, will take down your opponent's shields allowing you to kill them with two melees. This is supposed to serve as a batarang of sorts. You can use grav lifts to get up to the gargoyles and flares to blind your enemy. If you manage to move around unseen then you may even manage to get an assassination or two.

The map itself is quite small and because of that it is only suitable for 2-4 players. But don't worry, playing with a small party is great fun.

Strategy Guide (Batman)

Attack

Double Blind

Grab a flare and approach a henchman from the front, charging your plasma pistol. Throw your flare at him and shoot your charged plasma shot straight after. Proceed to melee twice.

Crouching Tiger, Hidden Bat

Find a corner where, when crouched, you are hidden. Wait here in a crouch until a henchman walks past. Melee him in the back or if that goes wrong fire a charged plasma shot and punch him twice.

Death From Above

Gain access to a gargoyle via the deployable grav lifts. Move around them until you find an unsuspecting henchman. Jump down and beat him senseless.

Evasion

False Trail

Using a deployable grav lift alerts the henchmen to your position, unless you're smart. Throw a grav lift down and leg it down to a lower level, they won't suspect a thing.

Run Batman, RUN!

When you've been spotted you have two options, fight or flight. If you don't fancy ending up on the wrong end of an assault rifle then a mad dash across the map should lose your attackers.

Out of Sight, Out of Mind

The most obvious strategy is to stay out of sight. Use the markers to track the henchmen's movements because if you can see them they can almost always see you.

What Not To Do (Henchmen)
Do not leave your back exposed
Do not trap yourself
Do not lose sight of Batman
Do not ignore your teammates
Avoid doing these things and you may just prolong your imminent death.

Issues

There are two issues:

1) The map is escapable. However, there is no incentive to escape the map and in all of the games I've played on this no one has even thought of attempting it.

2) There is a spawning issue. I have tried many different things to solve it and the only one that seems to work is that all of the players have to die at the start of the round. So you will fall from the skybubble before spawning inside the map. If anyone can find a way to fix the spawns properly then I would be very grateful and would give them credit in a V2. The specific problem is that, without dying at the start of the round, people always spawn in the same place meaning that everyone knows where batman is.
