Slamer is a multiplayer mod, in this mod, you have only : a Melee, the GravityGun, and the most important the "S.L.A.M" the but of the game is to "Blow" your enemies with an Old-School way ... explanation : in HL2dm, a lot of people don't use the S.L.A.M. in our mod you are forced to use it, there was a lot of games which the Tripwire was used regularly like in "Duke Nukem 3D" or "Half-Life 1" but the spirit of the Tripwire has gone ;/ ... here, the S.L.A.M is the Most Useful weapon.
Here is the Alpha of Slamer, for yet, there is only one Server, Hosted by Thomas67, but no Bot supports, play with yours friends ;)
