You can set up an Online Hosted Game! I suggest changing the match settings to Deathmatch, 10kills. BEFORE you start the match, hitting
or
will allow you to choose your preset gun and start the game!
You start with 4 unlocked weapons, but you can unlock more weapons the higher your level is (check
Tips below). The random items that spawn on the map should count though so look out for the Large Sword, Laser gun, etc, but I wouldn't rely on it.
Get 10 kills, pick the
"quit" option which will send you back to the game-setup options. Setup the match again (deathmatch, 10kills) and remember to hit
to change to the next weapon. Continue doing this and the achievement will unlock after the last weapon's match!
Tips*** Spoiler - click to reveal ***From the main menu go over to "Profile" and the default should be the "Unlocks" page.
Scroll down and you'll see all the weapons, maps, and gametypes you can unlock. Level 17 is the max level which you will be able to unlock everything. Which you can level up by doing Online matches (I hosted online matches and double-boxed).
