Take up the mantle as the Shrapnel Sentinel, an ultimate defender of a condemned realm. As long as the pillar stands, the Sentinel shall too.

Use fantastically crafted weapons of energy, manifested from powerful cores, to take on unrelenting waves of robotic foes.

Those who summoned you know what makes a good defence - you will be armed with up to 4 weapons to take on 6 sequences of challenging onslaughts.

Persevere through your assigned trials, to reach the rewards of more weapons & upgraded powers. But beware, as your own abilities grow, so do theirs...

You will be pitted against others, in a bid to achieve the highest scores amongst global leaderboards. How far can you climb above others who have heeded the call?
