Platform is a deathmatch mod for Half-Life 2 which brings a new perspective to the gameplay. So far most of the weapons are the original HL2DM ones, though some have been heavily tweaked, and will hopefully be replaced completely in the future. The mod features deathmatch and CTF modes, with dozens of changes and additions to the gameplay to accommodate for the platformer style. The video is a bit outdated and doesn't show everything, but I'll try and get a new one up soon - and the mod itself should be released publicly in the coming weeks.
