1. A flashbang grenade that really flashes and stuns all enemies(and some close range friendlies) rendering them useless until the flash wears off.

2. Ptolemaic Spec Ops soldier from MS as an actor.

This one?

You'll need how to know the basics of making actors by dragonxp.

Worth a shot, and yes.

Ok I'm going to try it now thanks for the sprites, I have a framework.

Feel free to use my soldiers ripped from metal slug as template

Yes I am but it is tough, I couldn't figure out what to cut-out and what to fabricate.

EDIT: Head's only the easy part.

You only have to rip a decent viewable version of the torso,
4 arms, 1 hand, 4 legs and 4 feet. Following the example of ronin soldier sprites.
You can also do a background version of it darker to add fake deepness.

Also, if you think that part is hard, you'll see when you arrive to walkpaths...

Which the modding community would be glad to help, right guys?

Probably, but then what about the flashbang?
