[UI] PVP Protection, Healing Mines, Multiplayer waves

PVP PROTECTION
So well, the game is essentially PVP, though however..

there should be protection to players just wanting to PVE, like something they could purchase or buy that prevents other players from targeting them. Since a player can be killed 20+ times by the same person because of missions. Even if the enemy gets NO reward for the same kills over and over again its still counted in the missions.

The only players that benefit from the PVP are mostly UFE. unless theres some kind of Limit to WHO you can attack by level or something.

HEALING MINES
Basically mines that instead of damaging the player, it heals them a good amount of HP/Shield.

MULTIPLAYER WAVES ( FOR players who cannot spend that much Uridium and can only purchase enough to be FE )
These could be great for players who aren't really UFE, the Waves can be either accessed through Normal missions.. with different aliens. I know HADES can be played with multiple players, but at least give something to players who can only play a little or spend a little in game.

( The info above could have wrong information. This is just a suggestion nothing more xD )
( THANKS! )
