City of Brass reminds me of a 3D version of Spelunky from the millennium. As you sprint through its glittering, procedurally-generated metropolis, you'll find treasures, buy items, set traps, whip enemies and smash your scimitar at any cost. It's been in early access for almost a year and now it's on Steam, with the 1.0 update it adds the final boss fight.
As you can see in the trailer above, your whip is perhaps the most important part of your kit. It hurls opponents back to make room, and you can use it to grab parts of the environment, jump over gaps, or get out of the danger zone. It looks like you could upgrade it to add different effects to freeze or set enemies on fire. Presumably this will be controlled by geniuses who trade for goods or give you the power to boost your powers.
Unlike Spelunky, you will not have much time to think in City of Brass. You're running against the clock, meaning you're always between a series of mini-bosses. You will face many opponents at once, and you will have to slide or jump to avoid environmental hazards like spikes or moving blades. Everything looks reasonably fast.
In addition to the final boss fight, Update 1
The first user reviews are positive, as you would expect from the team that also did underwater, and Tom enjoyed his time last year. Much of the team of developer Uppercut Games also worked on Bioshock 1 and 2 at Irrational Games, so expect a high degree of shine.
It's $ 19.99 / £ 15.49 on Steam.
