If you’re thinking “Doesn’t the PSVita already have a native Duke Nukem 3D port?”, you’d be right since it does.
However, Duke Nukem 3D Megaton Edition was taken off the PSN store over 2 years ago and it doesn’t have nearly enough features as Rinnegatamante’s EDuke32 port especially with the latest update. EDuke32 1.5/1.5.1 for the Vita brings about:
Mod support which is one of the main selling points of EDuke32!
An update to a more recent version of EDuke32 (r6862)
Higher quality sprite rendering and fix for graphical glitches like mirrors not working as intended
Support for add-ons like “Nuclear Winter” and “Duke It Out in D.C” which are great if you’re a Duke die-hard!
Many other improvements like an increase in available RAM, bilinear filtering to the final rendered framebuffer and more more!
The above are all features brought by version 1.5. Version 1.5.1 brings about a bug fix regarding memory allocation, a fix for a crash relating to autoload and the ability to give savegames a name.
To grab the latest version of EDuke32, you can download it via VHBB or by following this link to its VitaDB page. You need original Duke Nukem 3D files to play the full version but you may obtain the demo files for free.
