1. Okay, so i was thinking, what if we had some different game modes? Like CTF, Tag, and one where one person tries to hold on to a ball, or an object, and everyone else, even people on his team try to kill him. The longer you hold the ball, the more points you get. You could use this by doing like /callvote gamemode CTF; Tag; etc. We could still have TD, but spice it up.
2. So i have been looking, and i don't see hardly any things about flying aliens. This gets really annoying because humans just jettard the open maps, and it makes it impossible for aliens to win, (Unless we have a really good advdrag or something) so i was thinking, like what rota said, a kind of vampire bat, or something like this:http://img32.imageshack.us/img32/5951/alienfly2.jpg, but smaller. I also think that it should be able to wallcrawl, or atleast grip the wall for a set amount of seconds, so that my next idea could maybe be implemented.
3. My last idea is a cool one. What if we could have certain aliens be like the basilisk, and grab on to humans? Kind of like a leech, but they could drop on to him. The human could still move back and forth, and look around, not impeding his movement at all, but while it was attached it would drain the life force, like 5hp every 2 seconds. You could get it off by mashing the spacebar, or having a teammate shoot it off, or something. Higher upgrades = More damage in less seconds, like 7hp every second? It would have to be untargetable to turrets while it was attached, or have it hurt the human while it was shooting it. I was thinking 75-100 hp, for the norm and adv guys.
Thanks for reading my ideas!
