Nerf Arena Blast was developed using the Unreal Engine. It's weapons are mostly modified versions of Unreal Tournament weapons, and were made to be much more family friendly. In this game instead of kills, the opponents will disappear and leave a point amount behind. The player who is in first will leave behind 1000 points, second place will leave behind 750 points, third place will leave behind 500, and everyone else will leave behind 250.
- Point Blast - Similar to the "deathmatch" mode of other games, but instead you must collect the most points by tagging out other players.
- Speed Blast - Speed Blast is a racing mode where the players involved try to be the first ones to collect all seven flags in order. when you get "tagged" you re-spawn at the last flag you touched.
- Ball Blast - In this game mode players must try and find six different colored balls throughout the arenas, then shoot them into a target. Once a player has shot all six into the target one final gold colored ball will enter the arena, the winner is the player who has shot all seven balls into the target.

Nerf Arena Blast uses a modified version of UnrealED called NerfED. The editor works in the same way, with the difference being the Nerf weapons in place of the Unreal Tournament weapons. It also has a few other additions such as the point targets, and the support for the new Nerf Arena Blast modes.
