Deathmatch

Deathmatch is a mode in Halo Wars Skirmish or Multi-player where everything, from infantry, to ground vehicles and airborne units starts off fully upgraded: however, Leader Powers will automatically improve over time. The player has 15000 Resources and all technologies start researched, the population total starts at 15 and increases by 10 for each base that is claimed with no limitation. Population however cannot exceed 99, so for example if you capture 8 bases it doesn't grow anymore.

Trivia

 * When you reach the max population of 99 playing as the Covenant you can have up to four Scarabs.
 * Deathmatch is better when played 1vs1 in very large maps such as Fort Deen, Exile and Frozen Valley.
 * In Deathmatch mode all of the UNSC leader's economy bonuses are rendered useless, because all of your units and buildings are already upgraded.
