Roadkill Rampage Achievement in Halo: The Master Chief Collection

This Multiplayer medal is represented by a bloodied stickman inside a yellow diamond and is available in Halo: Combat Evolved, Halo 2 Classic, Halo 2: Anniversary, Halo 3, and Halo 4. It is awarded to players upon hitting and killing an opponent with a vehicle (Warthog, Gungoose, Ghost). Despite being available in all the games, this achievement requires players to earn Splatter medals in Halo 2: Anniversary matchmaking only. Unfortunately, there is no easy way to boost this, so be prepared to play on Bloodline and Stonetown a lot, as these are the only two H2A maps that house vehicles.

When working on this achievement, you'll want to stick to the Big Team Battle or Team Slayer playlists. Both of the aforementioned maps will appear in this playlist, though you'll come to notice that they have and extremely low probability of showing up. If you want to try other playlists, Team Halo 2: Anniversary and Halo 2: Anniversary Rumble houses Stonetown, and Lockdown's (found in Team Halo 2: Anniversary, Halo Championship Series, Halo 2: Anniversary Rumble and Team SWAT) stalactites often time net a Splatter medal when an Environmentalist medal is earned (though this isn't 100% guaranteed).

All three maps work well for this achievement and it's just a matter of which playlist you want to try out. If you happen to go with the two bigger maps, keep the following in mind: Bloodline houses a Warthog and Ghost at each base and there a couple Gungooses scattered around the map as well. As for Stonetown, there are two Warthogs, one Gungoose and one Ghost at the beach-side spawn as well as one Warthog and one Ghost outside the perimeter of the complex. Splatters may prove to be quite the burden when playing Slayer or Objective matches on these matches, but if you aim small and try to get at least three to five Splatter medals per game, this achievement will be less of a difficult task and more of a focused-grind. Once you achieve 100 Splatters medals, this achievement will unlock.
