Killsquad focuses on short sessions, a live contract system shared by all connected players, and action-style control. Upon entering the game, players are presented with a contract browser. Bounty Hunter Contracts are being offered to all the community in real time, so players can either select one, or tag along with other players to fulfill missions together. Players can join forces with their friends on Steam, or tag along with complete unknowns. These contracts last approximately thirty minutes, and can be anything from hunting a large boss creature, escorting units, defending areas, etc. Heroes in Killsquad are class-based, and always start each contract at Level 1. Passive and active skills are specific to each hero, and can be available from the start, or unlocked as the contract progresses. By choosing skills, players can adapt their hero to the contract they need to undertake. Heroes also have a numeric value, the Vector. Vector is a metric of how good is the equipment currently assigned to that hero, be it weapons, or additional power-ups called Gears in the Killsquad universe. The Vector of a squad is a metric based on the Vectors of its team members. Fulfilling contracts and using the bounty to buy new weapons and gears is thus key, as Contracts require a certain vector to enter. If your squad has a Vector number below of the recommendation for the Contract, survival chances are lowered. Killsquad is a paid title, and so there is no microtransactions or loot boxes: once the contract is fulfilled, players get a reward in in-game currency, which they can spend on better weapons or equipment for their heroes. Planets on Killsquad are procedurally generated in a way similar to Left4Dead: the layout of the map is built by an AI, which also controls the spawning of monsters, the quests offered to the team, the reward, to keep players engaged. Planets are considered as another enemy on Killsquad, and so the AI can also spawn disasters to hamper the squad's progress, from meteor storms to minefields and police squads.
Multiplayer
Killsquad is class oriented, and so combining different heroes with different skills is key to survival. Some heroes, like Kosmo, follow a classic tank pattern, with aggro, huge life pools and melee attacks, whereas others, like Zero, are healer-style characters, which allow the team to heal mid-mission. Killsquad currently has 4 heroes to choose from, with more to be added later. The game is playable solo, but this is used mostly for training, as the main game mode is 4 player co-op. As of today, local co-op is not supported.
