Audio bitrates are lowered, and textures are replaced with low-detail placeholders. The Result:
This is a 2D sprite-based arcade port. Sprites are small, and there are no 3D environments. The Experience: Almost perfect. Gameplay speed remains intact. The audio suffers the most—the iconic "Heavy Machine Gun!" voice clip will sound grainy. Verdict: The best candidate for sub-100MB compression. Highly Compressed Ps2 Games Under 100mb
