I have just found out that Chaos Faction 2 is near completion and DP is planning to release it around Easter. That's only a month or two from now! Hurray! (It's been like a year or two since Chaos Faction was released. It sure took a long time to make the sequel.)
Finger mode (unlocked by getting the achievement Pew Pew Pew) weapons do nothing fingers do something. Only weapon with a marked picture of a hand looking like a gun actually works...oh and c is an actual gun.
I don't know about making an ideas thread now. George Eade (the maker of CF2) has been working on CF2 for three years and has just released it. If it took him 14 months, and three years. to make CF1 and CF2 respectively, then CF3 will surely take some time to make.
