Like, a those games were there is a wave and you have to keep ahead of it?
Actually as a game mode, this idea sounds so fun!
Of course, the thing is how to depict that horde. Because if you keep spawning enemiesd the file could get really big and there could be a lot of lag. It should be some kind of instadeath thing i guess, you get engulfed by the horde and you die, the horde acting like a wave.
Code wise, we should need some kind of “trap” item with the letter Z and described as a zombie horde. So like, it would look like a horde in game, if you make it slowly advance to the west, and it would occupy all the terrain behind them, at the north of them, and at the south of them, and advancing to the east, one tile each minute maybe.
Hmmm, i think it’d be really hard but oh, it would be incredibly interesting and would add an objective, and also a lot of FUN!! things regarding trying to escape at the last moment.
Also if you get in the line of sight of one of the Z autodeath traps, it should start to spawn some zombies on top of it wich would not be affected by the trap and would try to kill you, simulating the actual horde.
