Ratchet & Clank All 4 One will release on 19th October across Europe. That's a Wednesday.
UK releases generally happen on a Friday. So Friday, 21st October? We're checking.
Confirmation comes from the European PlayStation blog. The post there outlines the pre-order goodies on offer: a T-Rex Morph Weapon Mod, flamethrower, Mr. Zurkon hovering ally and Sheepinator Morphy Weapon Mod.
Ratchet & Clank All 4 One focuses on four-player co-op, as the name suggests. You can drop-in and out of co-operative games either online or offline locally.
Mix that into the routinely high calibre of the series and you get "enormous fun", according to Eurogamer's Dan Whitehead - and a game that treats teamwork as a core mechanic rather than as fluff.
