Harbour Heist

Get your best equipment ready, because there is a new heist in One-armed robber. The Harbour Heist!

A new shipment of missile guidance chips and military equipment from Rodman has just arrived in the shipping yard. Find and break into the containers and escape with the equipment.

This heist takes place at night during a thunderstorm, breaking into the containers is not as easy as it might seem. Rodman doesn’t mess around when it comes to security. Inside each container is a lasergrid, to disable it you will have to find the password. And don’t even think about breaking into the container before you disable the alarm, otherwise you’ll be in trouble!

Grenades

Not only do we have a new heist for you, we’ve also got some brand new equipment for you to try out: Grenades! Three kinds of grenades, each suited for a different playstyle and heist!

Fragmentation grenade

The classic fragmentation grenade. Pull the pin and throw it, and it will blow up anything or anyone nearby when it goes off. But don’t try to pick it up after you’ve thrown it, once that handle flies off there’s no way to stop it from exploding, and you only have 3 seconds to get away!

Distraction grenade

Is there a guard that’s always in your way? And do you wish you could just make him go away, but you are just not able to take him out? Try the distraction grenade! Activate it, toss it, and a nearby guard will come and check it out. It will keep him distracted for a good 30 seconds.

EMP grenade

This grenade sends out a powerful electromagnetic pulse that will disrupt nearby electronics for 30 seconds. Use it to get past security cameras, disable lasers, or temporarily pause guard phones’ countdown.

Other explosives

In addition to the grenades we have also added explosive gas canisters, these are scattered around maps. Check out the Harbour heist to get an idea of how it is used, and will be used in the future!

Santa outfit

Map sale
