Well I was bored and I looked around and didn't see anything like this so I just wanted to see what you people think.
Capture the flag - Both Team Alpha and Team Bravo have a Flag near their spawn points. Each team must infiltrate the enemy’s base, pick up the enemy Flag, and bring it back their own Flag to capture it and score a point
Search & Destroy - Each round, one team must plant and detonate a bomb at the target site, while the other team defends the site.
Elimination - Your team's mission is simple: eliminate the enemy! All enemy forces must be removed from the area.
One Man Army - You're in there on your own, soldier... it's you against everyone else!
And if any douche bags say that I wrote all of this I actually just copied and pasted from the website.
