Pitch: Hexagunz

Basically, this would be Polyguns, but we would be more competent devs and actually update it.

Armor

Every piece of armor adds different stats. Health, weapon fire rate, weapon damage, movement speed, etc. Just like in Polyguns. However there are a few key differences. Some armors also take away stats.

Set Bonuses

Set Bonuses are earned when a player wears a full set of the same armor. Each set bonus is unique, and can be an ability, stat boost, or any other gameplay enhancing thing. For example, the Set Bonus of the Ninja Armor would be that your character makes no noise while walking or sprinting, while the set bonus for the Viking Armor could be Battle Cry, which boosts your attack power for a short time after a melee kill.

Weapons

The weapons in Hexaguns would all have to be unique. In Polyguns, many weapons feel exactly the same. This will not be the case in Hexaguns, as each weapon will have a determined purpose beforehand. Therefore, we end up with less weapons that seem too similar.

Maps

The only real thing that should change between the maps are the setting and layout. What I mean by this is every weapon should have long range sightlines, medium range sightlines, and CQC areas. They should only look and behave slightly different, and have different interconnectivity.

Conclusion

This would see an arcade like, simple, yet fun game. While it looks simple, it can be made fairly complex.
