Okay, time to jump ahead of myself.

Multiplayer isn't up yet, but I figure this will keep you guys occupied in a very productive way. I know how full of ideas you all are for mods, so this should be a piece of cake. The idea is that you specify a powerup for multiplayer mode in this thread. More details on the powerup system will follow, but I'm sure you get the idea. Here are the guidelines:

1. No comments on other people's powerups.
2. No non-proposal replies.
3. You may post as many proposals as you want, but keep them in a single thread as long as there are no other new threads in front of your's.
4. Read all other proposals first and don't post a duplicate.

Here is the format for a proposal. Follow this religiously (copy and paste this bbcode and replace parts in <<>>s with your own text:

[b]Name[/b]: <<Your powerup name>>
[b]Icon Design[/b]: <<A brief description of your powerup's icon image>>
[b]Type[/b]: <<Either friendly or aggressive (do you target yourself/teammates or enemies?)>>
[b]Suggested Level[/b]: <<A powerup can be of level 1-3 depending on its power.  3 is most powerful and requires most charging.>>
[b]Description[/b]:
<<What will your powerup do?  Include all details necessary to get a clear picture of exactly how it will operate.>>

Here is an example:

I also want to point out that if powerups that intentionally break combos are used, it could lead to an easy victory because of how the scoring system is based on the combo counter.

How hp and score is based on who wins or not?

Anyways,
Name: Random Autoaim (Can't think of a name It was just popped out my head while playing CS using awp and sniping moving opponents whenever I see one)
Icon Design: -;-? (Crosshair with a "?" beside it, looks like an emoticon)

-This activates on a spinner too.
-Skill will only activate up to three times(0-3) throughout the game.
-Too bad if the powerup activates in one note combo...
-This is not like relax mod that you still need to hover the circles.

This map has been deleted on the request of its creator. It is no longer available.

I think we should have teams like they do in EBA, but I'm sure you're already looking at that.
Name: Beat Heal
Icon Design: First Aid Sign
Type: Friendly
Suggested Level: 1-3
Description: I doesn't disappear when you click it: Rather it stays for a period of time and if you click it to the beat you can heal: Problem being that it does stay in a spot not occupied by the usual beats of the song and you need to keep up with the song also. Which is why this probably wouldn't be on harder modes.

Type: Aggressive
Suggested Level: 1-3, depends on effect eduration and line/splatter size, also whether the paint fades or stays
Description: The opponent's cursor leaves a colourful trail wherever it goes, which could fade after a while (or not). awp added the following: clicking on hitcircles leaves a splatter of paint there, which could fade after a while (or not). Aim is to reduce visibility, of course.

Huh. That gives me an idea.
Name:Flashbang
Icon Design:a thunder cloud
Type:Aggressive
Suggested Level:1-3, higher level increases intensity
Description:Once the player is affected, his/her screen goes white(but not enough
to completely block vision), and this effect would ease back to normal at a rate depending on the level.
Also, the player would hear a thunderclap(not too loud), and the music would become quieter,
going back to normal gradually, its rate depending also on the level.
The effect range would be 5 seconds for level 1, 7.5 for level 2, and 10 for level 3.
