Similar to the popular game The Binding of Isaac, this game is a dark themed rogue-like. While there's some clear inspiration there, Depths looks like a much faster paced shooter that's over-filled with blood, explosions, and tons of challenge.
There's a huge variety of weapons and unique items to find and use, and your choices about what you buy (with in game currency) can drastically effect the gameplay. It features an original score by Bibiki, full controller support, and it has the always awesome benefit of local multiplayer co-op, so you can bring a friend to this action-packed adventure.
