Developed by In-Fusio, ExEn® (for Execution Engine), is the very first software dedicated to mobile gaming.

Small and light, (less than 100kb of ROM and 32kb of the RAM in its initial version) the software's main function is to download and run games on mobile phones.

ExEn® is very small footprint (only 5% of standard phone memory) fits in the mass market handsets.

ExEn® offers the very best video game interfaces for real time animated graphics and reaches a performance level 30 times superior to a generic virtual machine.

ExEn® turns mobile phone into portable consoles. Once downloaded, games display a fireworks of new features.

Working as a virtual machine, ExEn® is also a safe engine for handsets preventing many of security issues (viruses, crashes…) that occur when games are run locally. Part of ExEn®'s development is dedicated to security: the software provides built-in identification, useful for billing, statistics, data mining, customisation, etc..
