Been playing Quad Touch for a couple months now. It’s basically a suite of classic Quake engines that you can use to play the original Quake and Hexen 2 games on your phone. Pretty solid app if you’re into retro FPS games.
Here’s what you do: you can pick between different engine versions like DarkPlaces, QuakeSpasm, FTEQW, and more. Each one has slightly different features and graphics. There’s also a Quake 2 engine and an IOQuake3 engine – took me a while to figure out all the options but it’s cool to have so much choice.
Look, if you’re a Quake fan, you’ll probably like this. It’s not perfect – the UI can be a bit clunky sometimes – but overall it does the job. Worth checking out if you wanna relive the old school Quake experience on your phone.
