I noticed the PSOne Syphon Filters seem to be missing a noticeable amount of info, I was just going to say I am playing them allot again so as I come by new stuff I will edit. I also have been making videos to showcase the multiplayer and stuff for the multiplayer-based pages.
Yes, that's a wonderful idea. I'm very busy and therefore, I can't really add so much new material. But lot of things about enemies, missions, weapons (etc.) are missing from here, preventing this wiki to be the biggest resource on Syphon Filter.
Feel free to ask me if you need some help regarding the technical side of this wiki (templates, etc.) or anything else :)
And thank you very much for taking the time to add information here :)
