Hype Train was an event that lasted a few weeks. People bought special DLC to "fuel" it among other things. When they added skins and the loot "safes", they got something special, which ended up being shit. They apologized later with special masks and the like.
Raid is a game by Lion Game Lion, who did a number of DLCs for PD2. Imagine PD in WW2, but on the PD1 engine. It had no updates for years after release until fairly recently.
Walking Dead was supposed to be their next big game. They flubbed it hard, costing them the contract and planned purchases.
I can't recall the VR headseat, but it was a bet by one of the heads to get into that area. It failed to where you can only find those headsets in that office/city.
