Check out the first gameplay trailer for Sanctum 2. In celebration of a trailer well done, the four heroes of Sanctum 2 spend the last 20 seconds or so wiggling their posteriors as a robot army crawls menacingly out of the sea. And who can blame them?

This is a brief but exciting blast of gameplay footage from the tower def-FPS sequel, and a welcome surprise after that tantalising teaser trailer the other week. In it, we see far the game has come since its 2011 predecessor. We also see a big armoured crab-robot, who will likely be a right git to take down.

As IndieGames point out, Sanctum 2 will feature an in-game graphic novel, an expanded survival mode, and more aggressive enemies that will attack the player/s on their unrelenting march to batter your power-core. It’s due sometime this year, the exact date presumably depending on how many turrets you’ve placed in its way.
