BioShock Infinite

BioShock Infinite Achievements

Chain Reaction

Damage fifteen foes with an exploding enemy, using the Radar Range in Burial at Sea - Episode 1.  

The Radar Range is a new weapon in Infinite. It's found in the Housewares chapter after taking the tram. Through normal story progression, you will eventually enter a shop called The Bistro. When you're in The Bistro, part of your objective is in the basements kitchen area. It's also where you will find Audio Log #14: The Kiss.

Here, you'll find a code locked door. Enter the code 3958 to unlock the door and collect the Radar Range inside.

A group of 3 enemies will spawn behind you immediately after getting it. Aim at an enemy and hold down until the enemy turns completely red and explodes, damaging the other 2 enemies in the blast radius. This will count as 1 kill towards 'Cook and Serve' and 2 towards 'Chain Reaction'.

From here, you can continue to play normally, and use it whenever you fight groups of enemies until you unlock it. You can also reload the checkpoint and repeat on the same group of enemies until they both unlock.

Ideas anyone? I see no point in this dlc where this might be possible to achieve!

It's not 15 in one go, so should be fairly simple as long as you're aiming at splicers that are close to others.

As #2 said not 15 in one go but 15 overtime.

It's in the Bistro, in a locked room with the 4-digit key code pad.

#4 - Radar Range is not a vigor/plasmid but rather a 'gun'.

As with others, you these stack over multiple run-throughs, or from loading checkpoints. No need to get them all in one go.

Could someone please tell me what the code is to unlock the door to this weapon. Thanks in advance!

The door code is 3958 for anyone stuck on it.

Easy as hell. Grind it out as soon as you get the weapon then restart last checkpoint so you have ammo after unlocking the Achievement.

Ok, can anyone tell me how you guys found out the code to that door (other than the internet)? I was searching for that damned code in-game, nothing

When you enter the area, there is a crashed lift. Check inside there, there's a tape that explains why it's there and the code.
