According to my Calculations, It's possible to make new hacks If the coder is fully experienced or a PRO, So I'm here to share my new Ideas for new Features, I've been thinking this since last night. I hope some coders helped this idea, and you can make this hack. Note: I'm not forcing you to make this hack, I'm just sharing my ideas, No Offense.
New Ideas:
1.) Remote Controller Grenade - allows you to control the movement of the bomb and the time it will explode.
2.) Walk in Air (In any Directions) - Without Getting any error.
3.) X-Trap By Passer - This feature is optional, and this is illegal. I might try this after I've become 20+ Years old.
4.) Killall - Auto kills all of your enemies and their death would be your score (For example: 8 enemies died, then their death would be your score.
5.) Kill [ID] - You must specify the name of the player to be killed.
6.) Farmer - Allows you to create many bots
7.) Weapon Modifier - Allows you to Modify the Status of any gun, you have.
8.) Master Ghost - Only works in Black List GM Makes you permanent Invisible even when you're walking or Running, without Bunny-Hopping.
9.) STW(NE) - STW-Shoot Through Walls NE-Without Error, so you may shoot through walls anywhere without getting any errors just like the old days. When you shoot through metals you won't get any error.
10.) Transformation - Allows you to transform into Mutants or Titans you want, in any game.
I hope, I helped many Coders here, If I don't helped you then delete this post.
