CVG reports that there are four new multiplayer modes being tested for Call of Duty 4.
Bare-bones Team Deathmatch immediately took our interest, as it removes perks and kill streak rewards, leaving you with just your skills weapons to fall back on.There's even a chance that you can get in to test new modes. Simply head to the IAMfourzerotwo blog for more information.
Other modes included Hardcore HQ, which supposedly encourages more tactical gameplay and communication by increasing damage, removing the HUD and enabling friendly fire. Hardcore FFA similarly applied tougher conditions to the free-for-all mode.
Multi-bomb search and destroy was also tested, which blessed every member of the attacking team with a bomb.
