[2] It was also the last full length Funeral for a Friend album released featuring drummer/screamer Ryan Richards, who had been in the band since the Four Ways to Scream Your Name EP.

Two songs on the album – "Sixteen" and "Damned If You Do, Dead If You Don't" – had previously appeared in the band's 2010 EP The Young & Defenceless.

Explaining the album's title, vocalist Matt Davies-Kreye told Complete Music Update: "A friend of mine was mentioning how he felt that the best thing for the planet was for the human race to just drop dead and at times I can see and understand his way of thinking but a big part of me has this (probably) misguided faith in humanity to kind of steer the ship in the right direction for a change.

Bring The Noise (8/10) "...although there are heavy elements on this, the Welsh favourites' fifth album, the real theme running throughout the record is that of a pop-punk masterpiece."

"[10] Allmusic.com (3.5/5) "Welcome Home Armageddon has something that's missing from all the cookie-cutter screamo albums that have flooded the market in the 21st century: an honest to God sense of pop/rock craftsmanship."
