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.
