Game servers by the hour. Pay only when you play.
Spin up a Half-Life Deathmatch: Source server by the hour. Classic HL1 deathmatch on crossfire and the stock maps, free-for-all or teams, ready in ~5 minutes.
The original Half-Life deathmatch maps on the Source engine: crossfire, snarkpit, stalkyard and the rest. Free-for-all or Team Deathmatch, your call.
There are no working bots on this build, so it plays best with friends. Spin up a private box, share the address, and frag all night.
Snarks, tripmines, the gauss and the crossbow. Set player count, frag and time limits, and admin from the web console over RCON.
