The online services for Warhawk, Twisted Metal, PlayStation All-Stars: Battle Royale, and Sound Shapes have all had a stay of execution, which came to light when Ember_Rising on Reddit enquired of Sony’s customer support team. There’ll now be online access for all four titles until 31st January 2019.
From then on Warhawk cannot be played at all unless the PS3 is set to LAN mode for local network play, whilst for Twisted Metal and All-Stars, players will be able to play the offline campaign and local multiplayer. For Sound Shapes, players will be able to do everything they ever could, other than share their creations with the community or download user created levels.
