Assault has always been one of my favorite game-types in Halo. Was really sad to see it missing in Halo 4. I don't know if anyone else has attempted to re-create it or not. I've not bothered to check. So I've gone ahead and attempted to make it myself. Turned out to be pretty simple.

I started with the Grifball game-type and adjusted it a little.
Arming Time: 15 seconds. I did this because players can't sit on the plant plate to arm it. Instead it plants instantly giving the Planter a chance to defend the area. Once armed, it counts down.

Disarming Time: 5 seconds. This forces the Planters to defend and rushes the other team to that capture to disarm it. Duh

Return Time: 30 seconds

Carrier Speed: 110%. Did this because I hate the whole slow-mo from past games plus with the throw option, it's useless.

Throw the bomb: . I left this in because I enjoy the option and often wished I could throw it. And lets face it, carriers never HAD TO carry it in past Halos

Pick Up: Instant. To hard to catch it if you have to press a button.

Score to win?2.

Rounds?3.

Multi-Bomb? No. Test proved this was impossible. Sorry

One Bomb?Yes. But there's a catch. To set your came up for One Bomb, you must place the Bomb/Ball Spawn at one team's Plant Point(Team A). This allows that team to quickly have access. HOWEVER The other team can still plant the bomb. This forces Team A to place defense more then then Team B if they grab the ball. This set up also helps prevent Ties.

Neutral Bomb? Yes. This is basically just like Grifball but with longer arming times and with disarm times.

Vehicles? Yes. Driving is enabled but as usual the Carrier can not drive nor shoot.
