toward the console's high real-time processing power. Across twelve months and with a budget of $1 million, Resident Evil 2 was ported to the console by a team led by nine full-time and one part-time personnel from Angel Studios. Further help was provided by ten staff from Capcom Production Studio 3 and Factor 5. This version offers features that were not included on any other system, such as alternate costumes, the ability to adjust the degree of violence and to change the blood color, a randomizer to place items differently during each playthrough, and a more responsive first-person control scheme. Additionally, the port features 16 new in-game documents known as the "Ex Files", written by Tetsuro Oyama. Hidden throughout the four scenarios, they reveal new information about the series' lore and connect the story of Resident Evil 2 to those of the other installments, including some that had not been released yet. The Nintendo 64 version adjusts its display resolution depending on the number of polygonal models currently on screen, and supports the Expansion Pak accessory for a maximum resolution of 640×480 during gameplay. Other visual enhancements include smoother character animations and sharper, perspective-corrected textures for the 3D models. This is the only version to use surround sound, with the soundtrack converted to Dolby Surround by Chris Hülsbeck, Rudolf Stember, and Thomas Engel. The team reworked the sound set from scratch to provide each instrument with a higher sample rate than on the PlayStation, resulting in higher-quality music. Some features from the other enhanced versions based on the Dual Shock Ver. do not appear in the Nintendo 64 version, such as the "Extreme Battle" minigame. In 2018, Eurogamer called this "one of the most ambitious [and impressive] console ports of all time". Other versions A port of Resident Evil 2 for the Sega Saturn was developed at Capcom, with plans for it to use the console's 4 MB RAM cartridge, but technical difficulties led to its cancellation in October 1998. Tiger Electronics released a black and white sprite-based 2.5D version for its Game.com handheld in late 1998. It includes only Leon's story path, and lacks many of the original game's core features, including cutscenes and music. This was the first Resident Evil game to be released on a handheld console. In February 2013, an unfinished build of Resident Evil 1.5 was leaked onto the Internet. Reception Resident Evil 2 received
