Very enjoyable game when the servers were busy - however nowadays the most you might get is a handful of people thrown in with the bots. And I've got to say, I think it's a complete shame, really and truly. It is an innovative and exciting premise a breath of fresh air from the litany of Terraria clones, army FPS's & FTPMMORPPGS♥♥♥♥THAT♥♥♥♥.
The problem seems to be that the dev's seem to no longer support it, as it's had no updates in a long while.
To make thinks worse the game still retains a fairly hefty price tag of €13.99 - which I think is idiotic.
What the devs should
be doing (if they have no intention of supporting it properly) is to be flogging it off cheaply in steam sales on a regular basis to increase the player base and breath some life into the game.
Currently as is, with so few people, I can't say that I'd recommend it for the price - however the game itself is brilliant fun and the level of co-operation I came across with strangers was amazing.
So in short, I am going to recommend this game on the games merits, but would either wait for it to go on sale or for the price to drop.
