A few of my ideas:
- Bows-- I think it would be great to have a Native American or (if they want to stay in the European character theme) a modern Robin Hood-type character. The bow has a lot of versatility as there are various type of arrows that could be applied (standard, flaming, caustic, explosive, etc).
- Status effects-- The slow of Thunders grenade is a good start, but the game could use some additional status-effect characters. A caustic character would be nice-- one with an ability to poison other characters and drain their health over time.
- Throwable melee weapons-- I would like to see a throwable melee weapon like throwing knives, shurikens, or a spear/javelin. The player would need to recover the weapon or wait until it reloaded in order to use again.
Would love to hear other outside the box suggestions from the community. Thanks for posting!
