All the reasons you should play this game!
On the edges of the map, level bounds are present. These are only visible if you are near the level bounds. These level bounds are present for deserters of the game. If you exceed these levels bounds, the player will receive a warning to return to the battlefield. If they do not return within ten seconds, they will be shot for deserting the battle.
Some of the maps contain high-energy or very hot areas. Be aware for this because they will inflict environmental damage.
