1. Teleportation Grenade
Has the same throwing range as the HE Grenade and the same timed fuse and still bounces off of things, but instead of exploding, it teleports you to wherever it is, be it on the ground or in the sky. Perhaps the model is two light grey hemispheres with a cyan center. These hemispheres stretch out, revealing more of the glow-y cyan center just before teleporting. Would be nice also with good particle and sound effects.
How to use: Equips grenade. Throws grenade. Player teleports when the time runs out.
Should not be able to teleport players out of vehicles or teleport vehicles with them.
2. Teleportation Grenade Launcher
Has a similar function to the Teleportation Grenade except the grenade must be set off by remote detonation (Alt-Click) and it has a longer range.
How to use: Equips grenade launcher. If player right-clicks when no grenade is present, makes error noise. Player left-clicks and it launches a grenade. Player may at any time right click and teleport to wherever the grenade is, whether in flight or landed. If player left-clicks as a grenade is already deployed, it launches another grenade and the old grenade shorts out.
Should not be able to teleport players out of vehicles or teleport vehicles with them.
3. Combo Push Broom
A push broom that pushes people not half as much as the original push broom. Holding down the fire button will spin as usual, but as long as you continue hitting the same person consecutively (Don't interrupt by hitting another player, bot, or vehicle.), it will charge energy. When you release on this same player, It will fire the same push broom projectile but release that stored energy in a push. The more you hit them consecutively before releasing at them, the more powerful the final push will be.
Others
I might come up with others later, but this is what I got for now.
