NeonXSZ

Also, there's great customization options: You can change how flight feels, how the entire station looks, as well as adjusting game speed, weapon damage or bot intelligence.

All of the weapons use your energy for ammo, but the results don't feel balanced into meaninglessness like in Retrovirus.

Despite the open-ended form of gameplay, NeonXSZ is ridiculously easy to get into for players of any skill level thanks to an approachable and flexible learning curve.

Graphics are nicely done, has a Tron-esque feel to it all, and at least running on Nvidia GTX 660 (Linux), getting steady 60FPS with smooth rendering, so should run on low-end boxes well enough.

But to be fair, they did spend a lot of time to optimize the CPU side already and it still runs at a good frame rate with those setting changes.

In general the sound design to me is very engrossing with its muffled sound effects and outside explosions giving you the feeling of truly being inside the cockpit.
