Versus in a coop game

With Brook released and loved by the community, I believe it’s time to try something new. I made a VMF viewer which everyone seemed to like, but there were also things I made that the exact opposite happened with.

Arcade

For example, I released Arcade as proof that Alien Swarm didn’t have to stay in the same genre of shooting the bad guys. Arcade took Alien Swarm and turned it into a shoot-em-up arcade game with a twist – the punishment for losing is death. Apparently, people don’t take time to look at the pretty scenery. They just want to win and be done with it.

Sarge's Party

8e8 had an idea for a game mode called Sarge’s Party. In this mode, instead of working as a team to kill aliens, the players split up into two teams and race each other to complete a series of obstacles. I took this idea and tweaked it. Instead of a portal for everyone to jump into, I made three side-by-side rooms. The middle room is neutral – everyone starts here. The left and right rooms are the red and blue team start points.

Once a room is full – 1 person if there are two people playing, 2 people if 3 or 4 people are playing – the door closes and locks. I’ve tested this with friends from the Swarm Armory IRC and it works well enough to avoid all race conditions caused by two people running into a room that can only hold one more person.

When both rooms are full, the barrier preventing access to weapons breaks and the three doors leading to the lanes open. Players can move between any of the rooms in their lane, provided that they complete the challenge in the previous rooms. The outer lanes are identical other than light color.

The center lane is only accessible if there are an odd number of people playing. It allows the “odd man out” to spring traps on either team, but only on one team per set of rooms. The middle lane has no access to weapons and does not spawn enemies.

The team that finishes an obstacle second gets an additional challenge in the next room. For example, the first room adds a shieldbug to the second room, the second room sets the third room on fire, and so forth. I’ve built three rooms so far – clearing biomass, killing a series of drones, and destroying a set of rocks with a mining laser – and am working on a fourth – a tattered bridge. If you have any ideas for rooms, I’d be glad to hear them!
