Unless you can make low poly models for GunZ I'd say no.
Your models contain
  • 175k~176k verts on a sword
  • 46~47k verts on a headpiece
  • 19~20k verts on a gun
  • 5k verts on a possible npc



If you could reduce it to 1-2% of the verts, then I could change my mind.
Also some more textures on finished models would be nice.
