If I have easy access to RE1 PSX reg and director's cut, will I be interested in what Deadly Silence has to offer? The idea of portable RE1 sounds AWESOME but what is this business about first person mode and are Crimson Heads added? I'm so confused as to the true merits of the release, I really want to have a portable RE1 but are there a lot of glaring changes?
Deadly Silence is a pretty unique version of RE1, and it has alot to offer, even if you've played other versions of it. First off, there's no crimson heads, and no first-person mode. The gameplay takes place in third-person (via fixed camera angles), but if you're playing "Rebirth" mode, there's a knife slashing mini game that takes place in first-person, and has you knifing zombies via the touchscreen. It's simplistic, but I've always found it enjoyable. Additionally, much like Director's Cut's "Advanced/Arrange" mode, Rebirth mode remixes enemy locations, and also changes many of the puzzles, making them more touchscreen focused.
You can also play Classic mode, which is the original game without any of these changes, but there are still some pretty big differences in gameplay. In Deadly Silence, unlike other versions of RE1, you have a quick-turn, a manual reload, and an RE4 style quick-knife that you can bust out at any time, and which doesn't take up inventory space. Also, the knife seems to have been buffed a bit in this version, as it swings faster and has a much longer reach than in other versions.
There are also some pretty big flaws with this port as well, unfortunately. The FMV's look awful in this version (very blurry and pixelated), and the pre-rendered backgrounds also look worse than any other version (they appear to have had their contrast bumped up considerably, and look both washed out and rather cartoonish). The music was also butchered (incredibly poor sound quality, a constant hissing that can be heard if you're wearing headphones, and missing tracks here and there).
TLR, Deadly Silence is a pretty cool version of RE1, with a lot of cool and unique features. If you're just looking for RE1 on the go, it's pretty solid, as long as you're OK with it's technical shortcomings.
Edit: one other thing I forgot to mention is that the character models and animations were completely redone for Deadly Silence, and there's also new costumes. They do look pretty great, even if everything else kinda looks worse overall.
